Race Tracking Your Supra - Information exchange

[ABQautoxer]

I think it is minimal Does it help turn in- a little
There are a ton of driver mods way above canards.

Much like another post, I've been doing this 23 years just new to this chassis. I'm just asking about the car build aspect since I've never bothered with aero since my local tracks are lower speed but this car will visit more typical tracks. Thanks.

Dive planes are mostly for fine-tuning your aero to create more front bias depending on your preferred aero setup front and rear. Verus has informative packets on their kit in relation to their different offerings.

Thanks I saw that and think it's hugely interesting. I guess I should fully explain there is some complications here since I autox heavily as well as planning to run this in SCCA Max at TTN along with a local TT series. I skipped the dive planes while I put on all the other bits and now concerned I'm going to regret it. Thats why I was curious of the forward shift was noticeable even if minor. Sorry for not providing that info upfront.

That depends. I wouldn't say it'd be a regret. It gives you the opportunity to run the car as is and tune the aero to your liking. If you make it through this season, or even some of the season, and decide that you would like more front downforce, adding these are an easy thing to do.

I was traveling so have been out of touch. No worries. Feedback is always good so will adjust my commentary as well as I think we have started a good exchange and sharing. It is not about who fastest or best driver etc. we are all still learning. Especially me as I am a relatively knew to the driving part. I did have an advantage of growing up in a racing family as my dad raced champ cars way back and helped work on the cars since I was a kid. So all this helps. A lot more topics to get Into!

I still have to get a proper seat ?. I’m totally dreading pissing the Supra computer & sensors off. Being it’s something I have the least control of. @razorlab has a great thread on how to put in a seat w/out all the alarms ? going off. I’m going to show that to my fav mechanic and see if he can replicate Razor’s process. And pick a seat… I’d love to stay as OEM looking as possible but know that’s going to be hard $$$.

I also want to keep the harness bar as simple and non intrusive (in the trunk) as possible. Razor and Rock have the Cusco (I believe). Love their look and setups! Have you done this yet @ABQautoxer ? I‘m not going to compete and just having fun.

Doubt it’s affordably possible but taking a seat in/out for track weekends would be sweet ? Just crazy thoughts & know I can’t have the best of both worlds.… Once this is done, then I can think about coilovers with adjustable ride heights and getting a pro to ride in the car to tweek my setup.

Right now I’m using a knee pad to brace myself on hard right turns, lol. Sounds crazy but it works! Saw another dude in a Supra doing this and was like oh hell yes! Until I can harness in…. So that‘s where I’m at

I will say I got a PM from a fellow Supra friend who’s going to Sebring for the 1st time ?. Anyone else going there or Homestead, please hit me up!!!! Would love to meet more of you guys (and gals) ?

Totally digging the basic theme of this thread to get more peeps out there! No question is too stupid & even someone like me can drive on track ? . It’s not rocket ? science. This car was built for it! It’s a great way to learn more, become a better driver and fall in love with this car.

All the other crap on this thread, everyone is doing for fun (myself included). At least I don’t think we have any pro drivers on here. So don’t think by any means the car needs to have any of this stuff to drive on track. I believe that’s @Todday1 theme at least… Enjoy our rides and have fun!!!! ?

Yeah Bryan and I have talked quite a bit on FB so I'm far less intimidated by the seat change so that's on the list for this year. I have a cusco bar I painted red in my car. I'm trying not to buy anything for a month or two to see what the car needs next from use rather than winter bench racing.

Once you have the bucket setup properly you could easily swap it in/out with the OEM seat. Just buy an extra oem belt buckle to put on the bucket so you don’t have to swap that out either.

That was actually my plan but I ended up just keeping the bucket in all the time. IfI drove the car more on the street I would probably swap it out.

If you do plan on that, I would recommend not coding out the seat airbag and location detection so that all works when you have the oem seat in.

morning, all
look, i went through forums, i did research, so i'm asking this to conclude my research. fair enough, right?
(to be honest, the only straight-forward answer i found was zrk's street car alignment lol)

camber
front: -2.0° to -2.5°
rear: -2.3° to -2.5°

toe
front: 0.0° total
rear: 0.2° total

good conclusion?

edit: stock suspension

 

[Todday1]

So I can ad that those are solid numbers. It depends a bit on tires as most of the track tires like camber closer to -3 as a min. But I have been at -2.8 front and -2.6 rear and is pretty good. On toe I have run 0 in front but the 1 degree toe in makes it turn in better very responsive, so if tires wear faster than what you think then could try both. Getting the tire to wear flat should be the goal so you are not cording outside or inside of the tires and if you can get there then it is getting great traction as it is using the whole contact patch. Rotating after each track day, fronts to back or cross rotation helps a lot but would have to have a square setup.

100% stock suspension with no camber plates or arms? I'm also assuming since you are asking in a track thread, you will be tracking the car...

In my opinion, I would always aim for more front negative camber than rear, so with the stock suspension, get whatever you can up front, and make sure the rear isn't more than that. Toe settings look good. I run 0.22 total in the rear.

With stock setup you are basically bound with what the front gives you.

thank you @Todday1

correct assumption!

to add some transparency, i was planning on following that same advice, "get whatever you can up front", which i've read people go up to about -1.9°. will be buying camber plates very soon. also, thanks for the additional advice!

Only possible /w camber plate. without camber plate, stock camber is about -1.8 in front when toe is at 0. in addition, changing toe reflects camber. so general rule of thumb is, change toe before camber.

Also, alignment is more of a preference that's depend on your driving style as other mentioned. i.e. my race car (non-supra) has camber over -4.0. I don't like the number but previous owner loved it. most likely, I will run test and may change it after.

Only possible /w camber plate.

Or aftermarket control arms. I had the SPL arms, everything else stock and no issues getting -2.8° up front.
