New owner, track readiness questions

[AndyK5]

Hello coming from a GR86 to GRC CE to Manual Supra.

Purpose of the car is 90% track 10% drive to track...maybe go to work.
Tracks I spend most of my time in are Buttonwillow raceway and Streets of Willow.
I value cheap track time including all consumables more than pure lap times.
Setups I usually like are -3 front/ rear camber. Stock height or 1.5mm drop. Stock suspension, stock wheels. Endless 650 fluid, track pads.

Here are the questions.
1) What is the camber adjustability of the stock suspension? From what I have been reading front is un adjustable, rear can get about -2? Can this car make use of camber or crash bolts? For reference I had -3.2 just using 2 crash bolts on the GRC. I'd rather not get camber plates or rear control arms as I can't justify the price of these metal pieces being sold for $500-$750.

2) What is a good square setup for the car? 18/275? 18/295? I like the 19 inch setup but shopping for tires is a pain and is expensive.

3) What are the cheapest tire brand and source in the stock or the square setup? For GR86 I used GT Radial Champiros which were a cool $120 per tire on 17/225. Again fresh cheap tire is better for me than $1500 Cup2s with 3 track days on them. I'll be absolutely destroying the fronts as I usualy come in to corners too hot and tend to understeer.

4) Brake pads and fluid is straightforward, how about brak ducts? My GRC CE had factory brake ducts but I see people are putting aftermarket ones on the Supra. Supra does not come with brake ducts?

Front is non-adjustable. I added camber plates and moved them in as far as I could without the top hat hitting the strut tower. It's not much, but better than nothing. I needed any bit of advantage I could get for the class I run.
"Crash bolt"?

2) What is a good square setup for the car? 18/275? 18/295? I like the 19 inch setup but shopping for tires is a pain and is expensive.

You will want 18s for track duty. I know you can fit a 275 with stock suspension. Maybe you could go a bit wider if you don't mind some mexi-poke. But I can't imagine it would be worth it unless you are trying to save .01 seconds from your lap times and IF your class allows it; if that's an issue for you.

No clue. I spend a lot of time and money for track days and no way I'd "waste" my time being there on anything that's not competitive during competition or at least competent for HPDE. Yours is an odd request that I've actually never seen. I'm curious LOL. On the bright side, you can abuse cheap tires. They won't really wear much haha. I'd suggest some coaching or at least taking it easy, if you know you are overdriving the car.

4) Brake pads and fluid is straightforward, how about brak ducts? My GRC CE had factory brake ducts but I see people are putting aftermarket ones on the Supra. Supra does not come with brake ducts?

On generic tires, you will not need brake ducts as long as you are using a half-way decent brake pad and fluid.

Keep in mind opinions vary and you will have 100 people telling you 100 different things and doing any of them will work. Just pick a route to take and go for it.

Cheap out or try short cuts on dedicated track car will lead to frustration and sub optimum performance

Pads and fluid and spend $ on seat time

1. Either front lower control arms or Coilovers / springs with camber plates for front camber. Rear camber has some adjustability already.

2. I run 295/35/18 squared RE71RS but some people run 275/35 or 275/40 squared. Depends on driving style and if you want more turning or more speed on the straights etc. I run 18x10.5 square but titan7s make a popular 18x10.7 square setup that’s very popular.

3. no knowledge here, I normally just run RE71RS. For longevity, I’ve been told maxxis endurance tires can go lap after lap

4. Verus makes brake duct mod

Front is non-adjustable as people have mentioned. The factory manual says you can replace the front knuckle to gain you about 0.5-0.7. It’s a few hundred per side. Up to you if you think that’s worth it. Otherwise just bump up the air pressures to reduce chewing up the sidewalls.

Wait. What?

 

[razorlab]

Stock height or 1.5mm drop.

1.5mm is the thickness of a grain of rice. Hope this was a typo. ?

Other than that, for what you are looking for, which sounds like tracking on a budget…

Kumho v730 275/35/18 all around
Project Mu Club Racer pads
Good fluid

and lap it. It will be plenty capable.

Lol yes...1.5 inch is what I meant to say Kumho v730 is the best tire I could find as well, need to invest in an 18 square setup for sure.

You could also try and find two pairs of 2.0L rear 18x10’s.

or… grab some TSW Imatra 18x10.5 wheels for $750

Bloke

2023 MT GTS Supra

I run Full SPL Line of components except solid diff bushes
Ohlins Road and Track coils + RSR cancellers
Eibach sway bars
HKS exhaust (just for the sweet sweet sound)
Endless 660 fluid ( will be changing to Castrol once i use up my supply)
CSG c21 and c11 pads (will be going to a cheaper option once these are dead)
HEI brake lines
Enkei GTC 02 in 18 x 10.5 wrapped in Nankang AR1 275/35 18
Run 3.5 neg camber front, 2.5 rear, 8 deg caster, zero toe front, 1.2mm rear toe in each side
Stock power train (honestly you dont need the extra power, wait till you can out drive what the car is capable of before tuning)

Car is legit fast as F**k no heat issues and i live in Australia so it is hot on the track, car is very stable and you can drive the balls off it. the corner speed with the above setup is pretty crazy.

Even when i only had stock everything except H&R springs and neg 2 camber all around it was very good (except front tyre wear with these settings was high hence 3.5 camber to stop rolling onto shoulder)

Just send it stock with a better track alignment and have fun.

I am in a similar situation but decided to spend the money on verus camber plates. I'll let you know how much camber I get once they are installed.

So, I always felt like instead of spending that much on camber plates, I'd just get coilovers. For about $1800 or so you can get great coilovers with camber plates, at least for a GR86. Not sure what the coilover situation is with the Supra.

I ran my Gr86 with -1.75 front camber for a year and I probably wasted more money on tires than I would have had I installed coilovers or camber plates.

 

[3TMagnetMan]

The GR Supra out of the box is a fun car at track. Just get an alignment and go to the track. Everyone has different opinions on drivability and feel at the track. Just drive it at the track and see how you feel and see what you need.

You will need coils + cancellers and lower control arms front, New brake fluid and pads + lines if you want to send this car properly and then rabbit hole starts to get deeeeeeeeeep!

I want to maintain near stock daily drivability. I also thought it would be a quick install I could do myself so the investment was not bad at all. The Verus directions are a bit misleading unfortunately as the last step aligning the strut in the new camber plate was impossible or me alone in my garage.
