Just got a 2011 is250 and the wife is complaining about the breaks not being the best. Took it for a test drive and it can definitely get more stopping power for sure. Gonna go the same route too. Thanks for the video and the details.
I don’t know since I really did this DIY to show the process. I have not had IS250 brakes for 11 years. I recently upgraded the IS350 to GS350 14” F-Sport brakes. More for aesthetics as the 350 is more than needed. It will reduce fade and provide a much firmer pedal and feel especially for the spirited brakers.
Lmao idk if you remember me but I’m the guy from the Facebook GC with the non moving car due to the AWD rotor problem. I’m glad you made a video teaching people how to do it so they don’t have to go through what I had to go through.
I just picked up a 2 is 250 this year . I am eager to perform many of the upgrades you have featured on your channel. Thanks for taking the time to share your insights and love for this fabulous vehicle.
Thank you so much for recording the process, I just did this upgrade myself and it was very well worth it. Your tutorials are awesome keep up the great work
Love the way that you recorded this with a second camera looking from under the car. Beware that there are shims between the caliper and the aluminum knuckle. They tend to stick to the caliper when separated, but may also fall onto the ground. Nice to work on a clean car like that. You clearly do not live in the rust belt.
Tuner with Kids lol. I always found it difficult to get a pair of big brakes form the 350, gs350, or even the ls460 in my area. And eBay is really expensive. Where did you get yours?
junk yard or Rock Auto. eBay has the calipers for $300 no core return (which is about the same price as Rock Auto without the core returned). ebay.to/2skMcIq
Great tutorial!! I really want to do this upgrade. I have a question though, I have a RWD 2011 is250, does it matter what year is350 brakes I get and do the break have to come from a RWD model as well???
Parts are basically same except you have to get 2012+ USA Spec 350 rotors, those are AWD compatible. Else you can find GS or newer IS350 AWD rotors. You can sell cause the hub area is vented in the back vs. RWD that is vent up on front side. I'll post some links in the video to some AWD rotors.
Do i need to put 2012 rear rotors on as well? Every site i look for awd rear rotors it doesnt tell + feels like breaking could be better and i set my ebrake best i could and car still moves foward when ebrake fully set..idk what the dif is in awd and non... Thanks
Always love to see you working on your is250.i have one question.does the torque spec for the banjo bolt also apply for the standard caliper?and the other torque specs also?
Do u need brackets when upgrading the 2nd Gen IS 250 to the 350 calipers pads and rotors?? What pads are best for daily Alkabono?? What would I recommend for complete brake upgrade??
Hey there I was wondering if u could help Not sure if I saw but are the pads the same for IS 250 or if I go with bigger calipers I need the pads for the GS 350 F sport?? Also anything else important I need to change?? Will it cause and abs or brake waring lights??
Planning to do this on my 2012 is250 AWD, I purchased some is350 front calipers, what year rotors should I run? 2012 AWD gs350 rotors? Don’t want to mess up and get the wrong rotors
@@TunerwithKids thank you for fast reply,i have this bending disc issue on my 250 and im wondering if this swap can fix it,i tried so many disc brands but even the brembo can be warped after 3 heavy breakings .Im not a track guy i just drive fast ,the only thing is that we dont have this is 350 model here in Europe..
Do you really need the shield for the backing? What will happen if you don't put the shield? I just thought that it looks nicer without it and more cooling I would think?
You can use the 250 one and trim and bend to fit. Don’t remove all together because the hub needs that as a spacer. Another guy I saw on FB took it off and the rotor was rubbing the calipers.
IS your car an AWD, if not, do those brake dust sheilds fit 250 AWD for this upgrade? Also where did you get the decals for the refurb calipers? Thanks
I’m RWD. Not sure on what shield are needed for AWD. You can probably order the newer IS350 AWD shields. Decals can be found all over eBay for like $5.
Hi...I am from Malaysia. May i know what is the size (diameter) of the IS350 rotor? I just upgraded my Malaysia's version Toyota Camry XV50 stock front brake to bbk, using Advics caliper maybe from Lexus GS350 or IS350 (i guess, not really sure because it is an imported used one) with 355 mm rotor, and the rotor is really heavy compared to the stock rotor...
Hello. Thanks for the awesome tutorial videos. I have a question for the front rotors. I have a 2010 AWD IS250, If I buy a 2010 USA Spec Rotors, would that perfectly fit the 2010 AWD IS250? Let me know if the 2010 usa spec rotors will fit. Thank you.
Hey I ran into an issue. When I installed the brake and rotor the driver side started to shake when braking. I tried replacing the rotor, brake pads, and caliper. Each time feels like brake pads shaked . I even bleed the caliper. Every bolt was tightened and double checked. I’m at a loss and about to shake the hub too right after the bleed the whole system. Any thoughts or solutions?
Did you check make sure there isn’t any damage to the hub assembly? You can try to unbolt that and make sure there is no visible damage. Only other thing might be worn bearings.
you have to measure hub runout... it cannot be bigger than 0.02mm... you should clean your hub perfectly, same measurement with disc mounted.. you have to measure it again, disc runout cannot be bigger than 0.05. If your hub is not perfect (runout bigger than 0.02mm) try positioning the disc another way and measure again..maybe you will be able to compensate both runouts hub/disc and stay
Hey sorry to ask so many questions but I just want to be safe than sorry. For this upgrade are the only pieces I need are the calipers and baking plates? I just want to make sure I don’t need a 350 hub or bearings and whatever else could possibly be needed?
All years from 2006 to present will work. All rotors too. The ones to be careful of is if yours is an AWD, then you will need certain year rotors to fit.
Hi, this might be a stupid question but.. can you confirm that the diameter of the is350 rotors is 334mm? I'm having trouble finding the dimensions. Thanks
Hey, Tuner I’m interested in doing the IS 250 to 350 caliper swap but I would like to also swap the the rear calipers as well. What’s the process on the rears if you have any idea? Or planning on doing the same as well. Thanks
What year is yours? The upgrade isn’t that significant so unless you need calipers and rotors, not really worth it. The IS350 parts bolt up, the dust shield needs to be bent since there isn’t an easy way to remove, plus the part is over $250/each.
If you already have then it’s bolt on. Make sure you have the brackets too. Need a set of is350 vented rotors and you are good. It uses the same pad as IS250.
Thanks for the tutorial - I’ve been toying with the idea of doing this swap for a while and you’ve cleared up a bunch of questions I had. I do have one question for you: does the OE IS250 brake master cylinder have any issue keeping up with the dual piston caliper? Or do you recommend upgrading that as well?
Quick question can I still the same rotors that the oem brake system of the is250 has? I'm asking because I purchased drilled rotors for the 250 and don't wanna have to spend more cash on rotors
Hey question, I’m on rock auto trying to order a rear and front set of rotors for 2012 is350 and there different colors lol. We’re you able to find the same color?
It’s all random based on brand and grade. Best bet if you want to match is to sand and paint the center hub areas in a high heat black. It will protect from corrosion. All other areas of the rotor will rust anyway.
Hi Binh Enjoy your clips Like your 🚗 Im in Aust. but the info is still relevant -same car Ive recently bought a 07 is250 manual & its really helpful to see owners working on their car's themselves Could you point out where exactly are the lift & jacking points on the car. Im too scared to jack it up atm cos i dont know exactly where is safe Thanks Mike (AU) :)
Hi Binh Thanks big time for showing where to jack up the car. That magnetic puck is brilliant. Big Thanks my man Cheerio & keep up the excellent work 😀👍
Where did you get your backing plates. I can’t find any junk yard with 350s. Is there a website you got them from or are there website where you can get them from? How were you able to get your hands on them?
Try Bell Lexus Parts in Scottsdale, probably best value and free shipping for $100+. I’ve been getting all my hard to find OEM parts there. The dust shields are like $45/each.
Just bought a 2014 is 250 , the braking is crappy I’m coming from a g37 sport with big brakes, I was thinking of doing this upgrade but adding 20lbs to each front wheel and maybe 15 to rears , plus I want to upgrade to 19 wheels =more weight to wheels for a already slow is250 I dunno 🤷♂️ nevemind
It’s only a 7lbs difference per front corner to go IS350 BBK. The rotors are 10lbs more but IS350 aluminum calipers are 3 lbs less than IS25” cast iron.
Also, rears don’t need upgrade. I think rear might be same 12.2 vented on all 3IS (Fsport). Base model has 11.7 solid. Not worth the upgrade unless you can get it free.
Ok my bad for some reason I took the 350 calipers to be 9lb heavier, and I read that the rears are different a bit bigger and thicker rotor , some people were saying u can upgrade the fronts and leave the rears some said it could be dangerous.
Naw...rears don’t do any rear stopping. It uses the same pads between the 12.2 and 11.7 with a slightly wider caliper and different bracket. The bigger rotors are vented vs solid. But overall no rear world difference.
Hi mate. I have been told to get a new caliper for the rear left of the car and also a new pin set? Lexus only have the pins so they told me they will supply the top pin and rubber boot but they said that the bottom pin on their systems its not applicable for the car. Does this bottom pin come with the new caliper? Please let me know. KR
Order a rebuilt loaded caliper with bracket, $50 at local auto parts. The lower pin is seized and very common issue with this car. Need to change out whole assembly with bracket.
@@TunerwithKids I am in the UK. We fit the Pagid aftermarket calliper on and kept the bottom pin from the old calliper even though its got play to it. Got a pin slide kit hopefully that bottom pin is the correct one because it was a nightmare to get.
@@TunerwithKids Another question, what about the bolts and nuts. Which should use the Is250 or Is350. I have heard that the thread is not the same as the long ones
Cardone 2 PCS Front Left & Right Disc Brake Calipers For 2006-2007 Lexus GS430 Will work on an IS250 2014 Base Model? I put my vehicle on eBay and it says not compatible, but When I put 2014 IS350 it says compatible. Any help? Thanks!
Yea it will fit. All 13.1 monoblock brake calipers from 06 to present are the same. It said not compatible probably cause you put 250. Since you are upgrading to 350, need to assume you have a 350.
@@TunerwithKids Thank you for replying! My question is that will 350s rear rotor fit my 250 awd rear without replacing the caliper ? what bracket you are talking about? Can I find it in any of your videos?
why you did not measure the hub and disc runout???? I also tough that the hub needs to be cleaned (surface) from the surface rost? I am just upgrading my is250 with 350 calipers but I am worried about the runout.... and my hub was stuck as f**.... I managed to press it out using 2 screws and pushing against the old rotor and the caliper mount "ears" (sorry for my english) .. hope did not damage anything.
My car is a FL car, so no rust of corrosion to deal with. That minor surface rust isn't anything as it will happen to cars anywhere due to the iron rotors and steel hubs.
Thanks again for an awesome video. Do the rear brakes on the 350 fit the is250 as well? If so, I hope you make a video on the rear too someday! Thanks!
They fit and it’s literally a bolt on if you get the full caliper and bracket. Just need to bend the dust shields back. It uses same pads on slightly larger caliper and vented rotors.
@Binh-Tuner with Kids hi, just found your video. I have the is350 f sport sedan 2016 but my brake stopping power is not great. I'm guessing, since I already have the bigger rotars, the only upgrade I can do is the brake pads?
These were repainted. When I painted them, the OEM coating was almost impossible to remove, even with aircraft paint stripper but wouldn’t come off. I just prepped and painted with base coat and clear coat.
@@HUIzanoNA like aftermarket calipers? Or pads/rotors? For all the IS’ there’s four OEM caliper and brake upgrades which are cheap. Yesterday Bell Lexus had a crazy sale for $300/each ISF calipers and $280/ea RCF calipers (possibly a price mistake) but I posted in the FB IS groups and probably created a huge ordering surge. They put the price back to normal now of $372 and $348, respectively.
can i run this with the oem smaller REAR rotor/caliper combo on the 250? and 2nd, would these clear a 18 inch wheel? i do not have oem wheels and wonder if aftermarket 18 + 33 would clear in the front. thank you
@@TunerwithKids sorry to bother but the rear rotors are bigger from the 350 as i just found some from a used car i went to. how did you get those to work? i was told the calipers were the same but just wider to compensate for venting but, considering the rear is also larger in diameter what would i do there ( & also the backing plate)
I bent the backing plate to clear the rotors. The calipers are slightly larger but use the same pads. It’s optional to upgrade those. The 2011+ Fsport 250 all came with the larger rears from 350.
Rock auto, eBay (check link in description), or local part store. The calipers are same from 2006 to present and used in GS and RC so plentiful. Average price is $75-$80 each plus return an old core.
Hey Tuner with kids, I recently bought rwd Lexus is350 calipers for my 2006 rwd Lexus is250. I was wondering if I can keep the stock is250 rear calipers and rotors with the front upgraded to the is350 rotors and calipers? Also if that works, am I able to put the rear Is350 rotors with is250 calipers in the back or will they have to be is250 rotor and caliper?
@@TunerwithKids Ok thank you, that helps me a lot. One more thing if you don’t me asking, I found a good deal on a four pack of is350 rotors for the front and back but I was wondering if my 250 rear caliper will fit the rear 350 rotor?
I have the OEM 17 inch wheels. I read on a forum that the IS350 calipers would not clear with the 17 inch wheels.. Is this true? Do I need at least 18 inch wheels to clear? Thanks.
I was talking to my mechanic and he said the existing wheel hub does not fit onto the IS350 dust shields. I got the shields with the same P/N as your description. Do I need to change the hub as well?
Naw. There’s no reason why it won’t fit. I had IS250 shields, IS350, and now IS-F shields. They all fit. You have to remove the hub, tuck the shields on and bolt back down.
@@TunerwithKids Thanks for the quick response! I had gotten the call about it from my mechanic since he’s trying to remove the wheel hub for me a few minutes ago and that’s what he said. I’ll get it figured out. Thanks!
They are all over the internet. Check my links in description. You can also check rock auto or local parts stores. They ar $75-$90 for rebuilt but have to return the old core.
I tried finding them I winded up getting some high performance ones that are specific for my car I’m gonna throw on and I guess rebuild the ones I do have. Every shop around here tried telling me I couldn’t do that.
is that brake line from the 350 as well? my 2006 is250 brake line does not have that extra arm attatched to it that feeds that second inlet beside the banjo bolt on the caliper..... can anyone help with this?
@@TunerwithKids thank you so much for your reply i could not find this info anywhere and i was nervous to do the job with the wrong hardware! also i have never had a youtuber actually reply to a question before so again thank you so much. I love your content you have some crazy talent when it comes to working on cars. i watch your channel and i think life goals. Just did the job today but my rear fittings going into my brake lines were seized so im going to have to cut it back flare it and put a new fitting on and hope there is enough slack in the line to just re-attatch it
Weird Question but lets say I want to do the reverse of this on my 2015 is350 f sport, I want the smaller rotors and calipers on the front for fitment purposes and less brake dust for daily driving, this should just be the same process just putting the is250 parts on correct? Basically going from is350 fsport front brakes to standard is250 front brakes, will I run into any issues?
Tuner with Kids RWD manual trans, the caliper is on but i think the rotor is hitting something theres metal shavings on the rim. Only happens when turning. I reinstalled again same problem..
