Race Tracking Your Supra - Information exchange

[Islindur]

This is going to be very dependent on how you like your cars setup but I can share what has been working for me. I prefer a more neutral car that isn’t setup to be oversteery.

I have the Verus spoiler, front canards and front splitter (not high DF version) I run 650lb rates front and 600lb rear (true coilover) so a little more rate in the rear than what you stated. This setup has worked well for about seven events this year as I got used to the aero. However, now that I am more comfortable with the aero the car has become slightly too pushy for me. I’m most likely going to go to 650 or 700 in the rear and see how it feels.

All last year on stock power and no aero I ran 550f/500r

The setup: neutral/slight oversteer balance, for sure not understeer.
I am in 2.0 too I should state so weight balance is different, around 725 front and 725kg rear, full tank without driver, so real 50/50, with me in is more like 49/51% Thats why I was thinking about slightly lower rates due to lower mass, the engine is lighter, whole cars weights 1450kg, not ~1520 like 3.0's. Tires are square 275/35.
Atm car with both sways set on soft is more oversteery. I wanna eliminate body movements which the car still has too much off even with both bars and springs, just needs proper coils setup.
I spoken with mr Ding, he recommended HKS Hipermax R which run around 780/1100, so even stiffer up front.

Also, I am thinking which route to take with front splitter as the car is still daily, so cant run anything too low, thinking between Verus/APR air dam/Sayber but they all seem so low to the ground Im gonna super scarp
them :<

Front Eibach bar only here as well. Divorced and I run pretty high rates on mine, max stiff setting on the bar. May try the middle setting for a session or two next time, just to see how it does. Very easy to get the car to rotate as I please, VSC and TC off. Actually spun the damn thing in a session this morning, first time in months.

Great pic! I know the subframe has to be dropped to put that rear sway bar in. So I get why the benefit doesn’t outweigh the pain in the ass for the majority. The mechanic I used was really inexpensive to do so. That’s why I did both.

Great job fully driving her. She’s definitely more wiggly & easier to rotate with the VCS off. TC off is a must! Your car looks the same as Bryan’s. Don’t see many of them with that cool 2020 red/white. Jealous of all you northern folks able to track right now!

For me only front sway was understeer mess, added rear and its way better. Still I need proper coils to eliminate body movements..

Thanks to @Evolution ’s recommendation I went with Ohlins. What a difference!

Tell me about this difference, what changed for better
Also, U run stock height, stock Ohlins springs or lower?

Quicker more compliant rebound. I was surprised how little the car is upset after running over a dip or rumbles. Less counter steering, faster back on throttle and quicker lap times. Sebring is brutal in general. I only had one weekend on them but wish I had done it sooner ?

The Ohlins springs are great compared to OEM or lowering springs. I was actually lower prior to the Ohlins and got excessive rub. The instructions come with track setting suggestions. We started there & my mechanic set it at that. I have yet to get my local pro buddy in the car. Definitely will next season!

Less body movements/no roll? I dislike this play a lot, I like Porsche-flat

Found another track supra in the wild. Was at Lime Rock Park with MassTuning on July 3rd. I was being antisocial because of the heat and humidity otherwise I would have come chatted with you in the pits...

Anyone on here? Plate is MAX ATK and had GridLife number stickers on the sides and GT class sticker on the back.

You got the point by, so…. That is good

She still rolls. But not like a skipping stone on water. Went from OEM, to lowering springs, to aftermarket coilovers. It’s noticeably different. I didn’t know how much better it’d be until after a few laps. Incredibly easy to push and adjust to at the limits.

How big of a diff between springs and r&t? Also, U got sways?

Could that be @decodeddiesel ? ?

I do have sway bars. I had those with my lowering springs. The Ohlins come with linear springs and are much better suited for the track.

Wasn't me, but he had my car. ?

He had a bunch of series stickers of some sort, but like Bryan said it was not the best weather for socializing.

He did roll past me in the pits and I gave him a big thumbs up and a "Nice car!". He saw me standing next to my Supra and smiled and waved. It would be very cool if he's on here.

Once you get more negative camber in front and go square tires with more grip on the front the rear will tend to be more over steery so you will probably want to reverse your tire pressure strategy at that point.

@Eyelise I definitely noticed this when I went to 275^2, but I like the extra rotation. My starting pressure that I've been using is 25f, 24r. I'm really enjoying this setup with the sway bars and stock dampers/springs.
