Swapping out 18” Fifteen52 Tarmac’s for stock 17” STi BBS wheels to see if there’s any difference in performance. What do you think I should put on and leave on, let me know in the comments below.
Wheel weight will effect acceleration but to a greater effect is deceleration and rotational inertia, "turn in response." Great video showing just how much the weight of the tires and wheels will effect the cars performance.
53 wow thats heavy. Get something lighter. Funny Dave "22b" and I were talking about rims in this size the other day. I run 235 40 18 on my wagon on enkei ekm3 5x114. I'm looking to do a sedan conversion. Wonder how heavy my enkei's are lol.
Andrew Berndt yeah I’m not sure what size was oem but I know what the sti rims looked like on the 06/07 stis. The gold bbs rims. I tried to get some for my 11 hatch when I had it before my golf r. OEM look is always best in my opinion for majority of all cars. Ones they use on other Subaru’s etc if that’s makes sense.
Go over Show! I work at a racetrack where the members have the top cars that can be Bought. One of their friends noticed I was starting to mod my '11 GV & I can sense at least one of them feels threatened. Haha It's alright, they have too look to find the employee lap times. My current lap time was after only 5 laps. Found out the hard way that I need to have at least a 1/2 tank of fuel so it doesn't starve. Looking at knocking off a big Lambo & an '05 Ford GT this season.
I just put a new daily driver setup on my '11 GV yesterday. Method MR502 w/ 245/45R17. Seeing this I am going to get the scale out & compare my OEM 18" Enkei that have Bridgestone RE-71R's on em for track setup.
In weighing the bbs setup, also include the spacer weight as its part of the rotational mass. 30mm spacer, I'm guessing ~3lbs each. For the 1552's my guess is 54lbs each. Performance gains would depend on a combination of overall diameter between the two and their weight. If both are equal, whichever is lighter assuming the 17's. Awesome vids man!
37.6 lbs. It’s so weird to see 1552 wheels so popular outside the Volkswagen community. 1552v2 has been a vw company for nearly 30 yrs. Their original name was VW Sport. Then 1552 before Brad closed the business for a few years. Hence the v2. I remember Brad talking about starting a wheel line. The first ones were reproduction of a vw factory wheel. The snowflakes. The tarmac were an homage of a no longer made Speedline model which was popular in the vw scene in the late 90’s that Brad had on his mk2 GTI. Bucky. The Turbomac’s would look killer in 17” on your subie
Tarmac 18x8.5 without the tires is 26.5lb plus that tire is going to be around the 49lb. But now you are going to have the extra weight from the spacers on the 17'. Good job Bucky😎🤙
Nice comparison. This is why I still run 16's w/ wrx front brakes and legacy rears rather than brembos. Gets the best braking for the wheel size and keeps the weight down.
Removing unsprung weight has such huge benefits! Every 1lb of unsprung weight that's removed can be equivalent to anything from 10 to 30lb of sprung weight (so I've read). Probably why your seeing such huge gains from a small change. All about those gains! 0.5 seconds is a leap!
If you want to slay all day, 17"s, and that size looks the best on GC and GD's. Despite that being said, I recently went back to 18"s on my GDA. I realized that is awesome for daily driving/weekend touge/track. Though heavier 18"s roll comfortably over all the messed up roads in the Bay Area. Also, added grip and stopping to combat against reckless drivers in traffic.
I prefer the BBS wheels. The thinner spokes of the 17's with those spacers looks rad! Plus less weight is always a +. Also, great job with the impact wrench! 😉😉😉😛
17" all the way, maybe even 16". depending on tire size, your gearing ratio would be decreased, which means faster acceleration. it's something that hondas live by. my ITR has a 5.0 final drive, which means i accelerate faster than those with a 4.7 final drive, or a 4.3 final drive. you should look into final drive gearing. another thing that really gets me excited is steering ratios... make your car's steering lock to lock faster improves it's drivebaility through a road coarse or auto cross coarse, and makes it overall funner to drive. i'm not an export in those matters, but just things that i know would make a car overall more fun in incremental ways.
Fifteen 52 looked lighter when you lifted it. Go instead of show but you could grab some revolution's made from magnesium compound which look dapper and was on the WRC Subaru back in the day. They are six spoke however if you like 6 spokes and rare to come by but you seem to have good connections bucky😉
OK, I am sure someone guessed 53.8 pounds already. Tell us what the weight was already. Those things are porkers and honestly, I may not get them now. Does anyone know if the 17" 1552's clear stock STi Brembo's? I have 18" Prodrive wheels that I tracked for a while on my Bugeye. I then moved down to 17" RPF1's and wider rubber. Less weight and it is so noticeable at the track. Performance before looks but some like it the other way around. Great video Bucky!
I would have to say 18's are 23lbs per rim. Tires at about 27lbs each. So right around 50lbs per wheel. I'm a fan if 18in wheels, but thats based on my driving style.
Hi there bucky thanks for the vid, lock down gets a little easier with videos like this. I loved the look of the tarmacs and am struggling to answer your question. Its a driving car so 'go' should always beat 'show'. However the use of spacers always worries me and the stress they may cause on the bearings/hubs. If this isnt an issue then i say 'go' as tbh they look great too. If there is then 'show' wins and id live with 0.5 sec loss on a pull. Typical british answer lol but theres always things to consider........keep the vids coming and stay safe.
Hey Bucky! Great video!! The weight for the 18" is 48 by the way! :))) The launches looked great! The bbs wheels look the best! I did not think so until that last shot of the launch!
If always ran stuff that was more function over form. Those 18’s look fantastic but I would stick to a 17 for the handling/speed and slightly taller sidewall.
I don't think measuring 2nd gear pulls is going to determine the difference 1 inch of rim makes. Having more tyre however will give you a smoother ride and pot holes won't be as big of a deal
Definitely the 17s!! I found 18s are good for sealed surface rallying and high speed cornering but for acceleration and mixed driving I would be on 17s... i have gone back to 16s on my version 6 type r but thats on standard sti suspension... love the content bucky keep it up :)
Definitely go for go,with 18s you will have more rotational drag,plus extra strain on the driveshafts.JDM GC8 Sti's originally came with 16.Your BBS's are of a P1 from over here in the U.K.
Tire selection also matters a lot so it depends if there is a brand/model of tire you want with 18s. I think they have the most options however 17s still have a lot, you do get more sidewall if you want that (I personally think 40 is the best sidewall height for street cars and 45 works well for mixed driving) but Bucky knows more than any of us keyboard warriors. On my 2015 I have 18s but would rather run 17s. However I believe the 18s weigh about 46 pounds.
I’m thinking 56.69 for the tarmacs. And I like both I’d say daily 17s and 18s (tarmacs) for meets or cruising with your friends with them high end cars! Also love the channel found it after I got my first Subaru! 02 bug eye wrx wagon. And I love it 👌🏼👍🏼
Are you confident in those spacers? Seem to remember that was one of the reasons you switched. Anyway.. I would love a Built not bought shirt, but you don't ship to the UK.. Maybe I could ship to my daughter in Philly and pick it up on the next visit. Thank you for the joy. Love to you.
Get some Method MR503 wheels Buck! My 2020 STI has 19x8.5 wheels that weigh a ginormous 53Lb. I’m getting a set of MR503’s in WRC size 18x8. Throw a set on Cup 2 tires on. Total weigh 41Lb. That’s a 48Lb unsprung weight loss! Like throwing a big adult man out of the car.
Seems like it's worth making the change! Personally, I dig how the stock BBS rims look more than the Tarmacs too. I'm guessing the Tarmacs and tires are right around 51.5 lbs btw
So... I am a huge fan of Fifteen52 wheels. But. They do tend to be a bit heavier than most! Are you attributing the better "Go" to the wheel diameter, weight, or other? Thoughts? I obviously prefer the look of the Fifteen52's, but the gains with stockers are incredible!
Theorhetically 17's would give you a more balanced performance spectrum for daily/track/off road. And 18's would probably be better for track as the tires have less sidewall flex. I will guess the fifteen52s are 55 pounds a piece
The Fifteen52 wheels look great on there but the BBS wheels look good and the lighter weight is great. What about a wheel in the same style of the Tarmacs but lighter? Regamasters maybe, but the problem is they're pretty damn expensive.
With the widebody, you need the 18" to make "the look". But you should get speedline turini, 18x8 at about 25 offset. I always said those 18" didn't really give the look the car needs, not that they look bad... but not doesn't hit the spot. wheel weight... I'd go with 56.2pounds (I'm used to metric.. but.. wild guess :) ) Always cool to see your content.
Bucky, gonna say 46.8 lbs and the 18’s look better on the street...but when you take it to the track/canyons def switch back to the 17’s! Still waiting for my “BuckYeah” sticker 😏
Should have weighed the 17s with the wheel spacers unless you were running the spacers on the 18s as well. The STI BBS Wheels are what I run on my bugeye and what my dad runs on his RSTI 👌👌👌
I have Advan RS-Ds on my Forester STI. The stock STI 18" wheels and tires were ~50lbs the RS-DS were 41. Mine are 18" X 8j et47 5x100. They look sick too.
43.6 lbs on the tarmac. Stick with the fifteen52s!! Or get Matt to hurry up and get those flowform Holeshots in the Subaru fitments and sport those in a 17”
Haven’t finished to video but wanted to guess. 52.3 on the 18”s? Your videos are always entertaining and I appreciate everything you do! From a skater and Bugeye owner!
54.3 lbs Wheels should be 29-31 lbs and the tires a little less then 25 lbs with the wear and tear. I like the 17 BBS wheels but I'm biased because those are the same as on my '04 STI and I know those only weigh 17 lbs each. 17's weigh less but the 18's are wider for more grip, maybe put some offroad tires on the 17's for the dirt and some quality street or semi slick tires on the 18's for the track. Maybe in the future you could talk your tire sponsor into giving you two sets of the same tires for each set of wheels and test them on track and possibly also on dirt. Thanks again for all the great videos! Edit: Damn I was close at 53 lbs.
Thinking any weight difference should include the spacers and spacer nuts. Didn't get a good look at the tires on the BBS wheels, but I bet you can find some lighter rubber to make it even better. Curious about the tire sizes, too. Smaller diameter really helps acceleration.
I like the BBS look. Looks more like a sleeper, tires will be cheaper, rims are forged strong, and classic looking. I say your 18" were 49 lbs each....
also for timing meausrements you should get a device call dragy on amazon. it's what a lot of youtuber use to measure their accelaration and other things.
Nice! 17s are much better looking to me personally (I have the same gold sti BBS wheels lol 5x100) roughly 44 pounds would be my closest guess in tire setup weight. sick video Bucky‼️🤙
