Not saying it isn't fine to track a stock car but it is much better to track a slightly modified car. Having stock brakes and tires only gets you 2-3 fun laps before a cool down needs to happen. Much nicer to spend some money on the right parts so you can have a full day of fun. We both know this from prior experiences haha.

 

Heck yeah. That's why we're all still here.

 

The good news from this video is that the platform seems very capable on track with some modifications.

The bad news is... well, watch the video...

 

That car had some issues, not normal issues.

 

all the bad news about the platform seams to come from this or this guy's boss's channel... first the toe thing, which other Supra's don't seam to be having, now this TC thing which other Supra's don't seam to be having... The TC thing is much more likely a one off BMW thing

 

Is it? If you watch it, they mention they had a bunch of people commenting and telling them they were having the same issues.

The bump steer issue with the pre 2021's is a widely documented issue.

 

Thats why I got a 21... No issues so far. Yes the car can be twitchy but its not a bump steer issue. Its a rwd with junk factory tire issue.

 

Isn't the one in the video a 2021?

 

Maybe? I had to skim through the video since I am at work so I didnt pay attention. But either way, he had other issues going on.

 

Like? Others seem to have the same issue.

It's not my intention to talk ish on the Supra, I'm actually interested in it as a possible next car so I'm following the teething of the new platform. If TC just randomly turns on after turning it off, that's a big issue. The car looked really fast and stable before that so impressive for sure. Sounds great too.

Of course, I am sure soon somebody will find a way to permanently disable it like they did on VW's, etc

 

See, that is the part I didnt catch. The Supra has 4 different traction control modes. Most people (those who dont actually own the car) only know about 2 of them. If all he did was put it in sport mode and traction control off, then traction control is really still on. You can disable all of the traction control functions by holding down the button for a couple seconds. Again, most people think that if you just push the button, its turns everything off but it doesnt. On top of that, I coded in a sport plus mode. It still limits throttle and stuff but lets the rear kick out quite a bit before kicking in.

What issue he seemed to have was it bouncing between different traction control systems. One part he would be in normal, then it changed to sport, then back to normal. I have not encountered that with mine.

 

idk, I'd wager that even with their explanation of what bump steer is most people wouldn't what it was or wasn't when actually experiencing it. Robert sounds like a smart guy (and is), someone with a Supra maybe got sideways unexpectedly a couple times, and remembered Robert mention some handling issue, and claims they have the same issue. you gotta remember we're dealing with the internet here...

and even the first model year, Jackie Ding's time attack Supra doesn't have bumpsteer issues... he's even made a video measuring it...

 

I dont think they should be using "bump steer" as the name of the problem as its not a geometry issue. From what I have gathered, when the rear of the car hit a bump during a hard turn, it hit the bump stop which caused it to unload the rear, sending the car sideways. The 21s have revised (shorter) bump stops as well as different springs and valving to stiffen the rear from doing that.

 

Come on man, I think every single review of the car in the mags stated this issue with the first year car.

 

Alright, got to watch the video in full. So yes, the one time it "bump steered" was when he was in the middle of a turn (going pretty fast) and hit a big bump. Looked to me like it bottomed out. He was also complaining that the traction control turned back on automatically and if you are driving, you cant turn it back off (I will try this on my way home). He did initially hold the button down before he started the lap but then it looked like he clicked it 2 more times which would have put it in sport traction mode, not everything off mode. In sport traction control mode, it greatly limits the throttle with the steering wheel turned and doesnt really let the rear kick out. Its pretty sensitive and you can see how often it was kicking in.
