How I Rev Match PERFECTLY without being a good driver 

Rob, GM abs has a huge reputation for going into "ice mode." This isn't anything to do with your tires. Look up the BMW Mk60 ABS swap and it is what you're looking for.

" Scientifically Speaking this car fucks" - Rob

You can tell robs a real one by the way he shows himself getting towed off track. Most people would edit that out to avoid embarassment. Nothing wrong with going to the track and finding out your not ready yet, thats how racing works

Do you purposely leave your trailer hitch ball loose?

You should torque your ball on the hitch up. 2:45 - 2:47 you can see the ball itself moves. As far as I am aware that should never happen.

Lift off oversteer is what you're looking for ;) Its a very real thing that happens, and is on all cars, but moreso apparent on others. This is why braking happens pre-corner, so you can let the car settle mid-corner to get back some of that rear traction. This is also why trail braking is a thing. Unloading the rear tires to get some more rotation IIRC

@Rob Dahm Please tighten your hitch ball... that's an accident waiting to happen.

The difference in the way the car goes thru corners on or off power can heavily depend on the type of differential as well as the gear ratios / powerband under load

New trailer looks really helpful. If your fuel tank has provision for a fuel level sensor, you can usually rig up a pullup resistor to convert the sensor resistance to 0-5V or 0-3V voltage. Then start with an empty tank, fill up one gallon at a time and note the sensor voltage. Depending how flexible your ECU or dash are, you can convert from voltage to gallons or just set an alarm to remind you to fill up when the level gets below X gallons. Be prepared that the fuel level will slosh around quite a lot, the OEM fuel gauges have so much smoothing they will be slow to respond when you refill the tank at the gas station.

Seeing you guys putting the trailer to use with all its features brings me joy. All the hard work and time you've put into all the cars, You truly deserve this and much more.

Great content Rob! But I'm worried about Isaiah, what's he been up to?

That mood lighting absolutely kills it. Superb Addition 👏🏼

If you want the rear to be more planted on corner entry weight shift, you can toe in the rear a little. Having it toed out makes your car 'slippery', or kick out, act nervous, shift wierdly under weight transfer and generally try to kill you. Toe in keeps it planted in the rear.

Rob appreciate everything you do. All the engineering and self teaching is super commendable. Have you guys ever toyed with the idea of doing a rotary swap with one of the 86 twins. A 10k 5-700 HP handling grip machine. A mild flat torque curve with max HP at redline. I can't help but wonder what you guys would be able to pull off with a platform like that

Bummer weekend. Happy you are living the "get to the track early" life now. It's a game changer for sure. Can't wait to see you at Laguna!

I just realized he might not be exhausted. Might be some super dabs

Rob don't forget. Pressure readings are measuring resistance, you don't necessarily want high pressures as long as you have high volumetric flow.

Rob would you ever track the Diablo? Maybe at a motoring club? I know thats your baby but would love to see that thing get some screen time doin what it was made for.

Rob Dahm, nothing but love for the content, been following a long time! Just wanted to make a polite suggestion, I have been transporting 20 years, I wouldnt trust those size straps ever to hold a car. They may seem fine but in an emergency manuever I would not trust them not to fail. Good properly sized straps are well worth the money!

4:48-4:58 is such a mood. Thank you for the video Rob ❤

I love the whole catalyst track overview looks amazing and is very insightful💯

Ahahahhahahahaha, funny as hell after everyone roasted him about his driving last video

I love the jumping around the cars on every episode!

Sounds like your diff preloads (too much decel) or your damper settings (too much rear rebound) are off? Could also be roll center/antidive depending how much you lowered it.

The on-power = more traction thing is quite interesting, thought I'd offer help if I can. To me, it seems to be caused by a suspension stiffness issue. I'm not sure how the weight distribution compares to a stock Corvette, but I presume the rotary (even with turbo and all other accessories) would be lighter than stock, leaving the rear end to be heavy. Off throttle, the rear end will want to pass the front due to too much weight transferring to the front tires, leaving the rear end loose and like a pendulum. On throttle however, the weight transfers to the back and gives enough traction for what's needed. (Think Classic Porsche 911) Other than adding/ striping weight to solve this, you can stiffen the front springs, and even go so far as to lift the front ride height/lower the rear. This helps keep the weight toward the rear for more bite. Tuning handling (without downforce) is 100% about weight transfer and how to manipulate it. Learning how to tune became much easier once I thought of it like that (at least for me). Hope this at least gives a few ideas! I don't remember the full journey this car has taken and what suspension mods are installed (or the full extent of your knowledge), so hopefully this didn't come off as classic "Internet Snob"

Dude I was like damn! Something bad happened. Who didnt put gas in it? Lol

Time for some rotor shaped tail pipes lol. Car sounded awesome. If the oil leak gets taken care of and ruled out but still experience the weird ABS behavior, believe you might be experiencing the dreaded GM ICE Mode. Terry Fair at Vorshlag has a solution for the C5 using a BMW ABS module.

Rough 2 days for sure, but man, that's how it is...especially with a weird engine swap car that is practically a bespoke build. A lot of trial and error. Keep killing it dude!

lift off oversteering, gotta be more gentle on removing accelerator pedal if doing so midcorner. If I am understanding correctly atleast.

HELL YEAH!

"Scientifically proven, that this car fucks😏" -Rob Dahm hahaha, i love it!

Rev matching via heel & toe (also known as "blipping") is a skill every track driver should know. Practice, practice, practice!

Let me tell you, rev match in a daily is a blessing. Really smooth ride

Always Cool Rob, Isiah and Joel!

Get yourself a Mr. Buddy Heater, they work great. The single bottles last about 4hrs do get the bigger dual bottle one. They have a wall mount also.

Sounds a lot like power off oversteer which is great in a front wheel drive car but rather disconcerting in rwd. Try softening the dampening / rebound in the front shocks or increasing it in the rear. Same with spring rates. Tyre pressure can make a huge difference as well. Less pressure in the rear vs fronts will also help induce oversteer when coming off the throttle.

Just having non-oiled tires might make all the difference in the way it handles.

Beautiful sound

I am glad I am not the only one to notice the ball having play in it. I ran it back 3 times and slowed it down to confirm. Lock washer should do what it do but best to double-check its tightness. The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank tighten to 250 ft/lbs, and for a 1-1/4 inch shank 450 ft/lbs.

Dudeeee the glamours on the Vette under the trailer are damn gorgeous

that camera setup for the car on track at 8:18 is nice

Ah sick! You went to dirtfish! Can we expect a vid on rally driving soon?

Pure Michigan ✊🏽✊🏽✊🏽✊🏽 I'm in Michigan and right now the weather sucks, no V action at all 😢

I noticed that the car lifts the rear and seems to get into positive camber during braking, you can see it leaning the weight of the car mainly on the outside of the tire, not sure if it is related to you lift oversteer but might as well look into it.

lol i love how honest you are, i fuking suck at rev matching so imma let this computer do that shit for me. work smarter mentality. love it lol. good shit and damn you got you moneys worth from that trailer. that awning and lighting is dope af.

God damit missed you rob

I have a 2019 ZL1, rev matching has me spoiled. Cool to see you could add it to old cars, I can't go back to the clunk lol

Hey they gave you a break, sweet. Welcome back

Daiuumm booaiiih that revmatcher is going to get the cops on y'all

Where has Isaiah been

7:20 Hey Rob, an idea, prepare the 4 rotor for Pikes Peak and ask him to drive, let's see what happens!

I rev match perfectly with help from this video’s sponsor, KEEPS

Such a dorkfish. Got to love him

"Scientifically proven that this car fucks" should be a t-shirt like yesterday 😂

hope you get the setup fixed! there's plenty of time left to be found once it gets dialed in! not sure what your suspension setup is but I have a feeling that light weight rotary up front is affecting the balance of the car, you might need to try different spring rates

Lets go early access!

you should try to get some legs for that awning, one good gust of wind will bend the roof beams and it'll never go back in

Judging by the symptoms, you have a healthy MR2 :D That suspension is fine.

That telemetry is so cool 😎

I would be interested in bringing out my mostly-stock, pretty much 100% factory parts C5 Z51 that I have set up for STU class (SCCA Autocross) to compare to the Rotary Vette. (It has Z06 suspension + bilstein b8 shocks, oil cooler and oil pan baffles, delrin control arm bushings, and different rear sway bar). Got laid off so road trip sounds fun :)

Can tire warmers be used as heated blankets? Asking for a friend.

cant say i know the rear hooking to the ground during power what it is but it sounds a bit like it got good amount of antisquat.

Trailer lights are great.

how does it know you are about to downshift? it needs to know before you release the clutch pedal right?

Giving it some gas while turning makes perfect sense. You always want to apply a tiny bit of aid gas in lack of a better word for it. Not really enough to accelerate but just to keep the speed. Helps keep the car stable when cornering.

Patreon crew unite!

AYE THATS MY White CRX in the background, and the car that spun out behind you lmao, sorry for photo bombing you 🤣

"This car has been sitting in the corner of the shop getting no love..." sad 4 rotor noises

2:14 best moment 🤣

It needs a big WANG! and reminder when you spin out… clutch in, hard on the brakes, when you just roll and turn around people may try and go inside (like that white car) and you will just smack into them

Heeey I was that white crx that spun right behind after you spun lol good times

Do you have the OEM interior door panels on this car?

How did I miss a rob video!!!?? RU-vid notification slacking

Building, tuning and sorting all vehicle's settings are usually diff steps. Rob does them all in one video. Was gonna say, "Get in with an instructor or like any of the top trusted pilots at the track to give you some car feedback. Either from the pass seat or driver's.

It’s about weight transfer. That’s how it works when driving at the track. When weight shifts to the rear due to acceleration there’s more grip in the rear tires. That one way to overcome oversteer. If you are oversteering hitting the brakes in the corner makes it worse.

Do people have issues with rev matching? if you can't rev match how are you even driving a manual in the first place?

FDs will rotate the same way off throttle but the FD chassis can attack corners better that’s why you experience lift off oversteer more FCs are where that shines through a lot and a lot of times sideways is the way you attack the course in an FC just due to how they want to handle (not overgripped) it’s like how the aw11s and ap1s had notorious oversteer issues is from lift in corners left foot braking helps a ton if you can dial in your technique cause you can start brakeboosting a little at the beginning of the turn in and take off way faster

bro your ball hitch is loose.

Session ended due to blinker light fluid leak @19:38

Tighten the hitch ball bro

Where is the 12 rotor content rob? Love all your video's,. But been waiting on 12 rotor content for 6 months

I think u an crew can an will figure out how to make better fittings for those things an even if higher oil pressure or gas pressure aren't need who knows how much safer you will feel an how much harder you could push the limits of all ur builds by doing so man yall got this ! 👍 ❤

What haltech are you running rob?

Ever looked into a "Toy Hauler" but for a car in your case? im sure they would love your reach into car venues vs just camping

How are you detecting which gear the car is in?

"Scientifically proven that this car fucks" 😂

Ik it’s sounds crazy (kinda counter intuitive) but lack of body roll of the chassis will cause u to have to gas it through the turns. when gas it it will force the suspension to tweak more and grip up on the outside wheels vs no gas u will scrub your tires and slide as your grips on the inside tires. Idk if u have any chassis braces or really stiff sway bars (specifically in the front) but I’d look there for answers)

I just got my first rx7 and bought a spare 13b, please teach me your ways!!!

You guys need the REI Kingdom Cot or Cabela's Lounge Cot to change your lives.

I’m ctfu every time I hear that fucking blazing saddles ass whiplash downshift 😂😂

The breakup coming out of corners is traction control im pretty sure. For the small investment, pick up a Chinese diesel air heater. They use so little diesel and pump out a bunch of heat.

Anyone know what's happening with the 12 rotor?

On this episode of Rob Breaks Cars, Rob breaks the rotorvette.

Have i missed something, wheres Isaiah these days?

Does FabDaddy Isaiah have any desire to drive on track? If he does he deserves a few opportunities to drive. Hes always at the track wrenching and filming but doesn't get to drive. I would get frustrated even tho I love wrenching more than driving its nice to get a chance to drive once in awhile.

So technically, a pimp is a butt.... Plug.

You know your killing it when your trailer is worth more then most of our cars.

k i need you to do this on my veloster. I'm so used to driving 18 wheelers and never touching the clutch, that i look like a baby driving his first manual in my car D:

Rob is real. No denying it.

Any one else noted the tow ball nut is loose? 2;46min in.
