or be cheap and get those adjustable hks springs.

Idk if HKS springs would help for clearance. On OE suspension a lot of square 18 inch setups contact the spring perch in the front

you need a 23mm spacer or something wacky like that with oem suspension. Having said that… just get some coilovers.

wow a 23mm spacer????!!! I feel like that can't be good for the suspension

I ran apex on stock set up for over a year with camber up to around -3. With a sport spring camber plates and all the adjustable control arms. No rubbing and no spacers. 275/35/18 tires. Yes the bigger stock/sport springs are closer on clearance and a 285 tire may rub if you have a lot of camber so would stick to the 275.

My Ohlins work but I’m only running 275s with 10mm spacers all around. One thing to consider with coilovers, are where and how easy they are to service. It’s good you’re checking all this out ahead of time ?

Here is a pic with 15” big brake kit. They fit no rubbing and hold up well to track use.

Lol at wilwoods. I like how the pad is only using maybe 3/4 of the rotor surface.

Ouch…. I never noticed that ?

On the OEM note (or any brand), how often do you change the caliper brackets, if ever? That was a maintenance item that would come up on my previous track cars.

OEM calipers bolt directly to the hub on our Supras.

when I run my 11” setup (Apex), I have to run 3mm spacers or they will rub front and back. That was on 315 tires though. We will see if I need spacers with my 295s if they ever come in.

Noticed the plastic around my hks tips melted on one side due to a long high speed left hander. Has anyone put any sort of heat shielding or material around the plastic to prevent this?

Hangers seem good. I can’t really move the exhaust by hand.

We're tucked in for the night at CMP. Wife's maiden track outing in the Supra on a fresh set of SC3. What's the hot pressure target for these tires?

Good to meet you and Maggie this weekend!

I guess it's a little too late, bit I would run between 32 and 34 depending on ambiant temps

Well sh!t. Not surprisingly, there are no PFC-11s for the G29 chassis. Talked with Josh at Bimmerworld and he said that PFC makes runs of 20 sets of pads when they get enough orders, and there is no timeframe when they'll get to that threshold.

With the ER-1 feedback from @AHP (Ken at KNS is a good guy...done business with him before), I'll skip them.

The final option, and again...I think I'm doing the guinea pig thing again - Pagid RSL29. It's another enduro compound, they are near-CSG-priced, but Bimmerworld had 1 set left.

A friend ran them on his C8 this year - he loved the feel and the wear, but it wasn't quite enough pad for that car. I'm thinking the Supra (with me driving) will be goldilocks and be just about right.

Pagid RSL29 report card: Plenty capable track pad, but completely different feel than the CSG. Coming from the initial bite of the CSGs, the first couple of braking zones felt really strange with the Pagids. I overcooked several braking zones through the weekend trying to do what I'd have done with the CSGs. They just don't have much initial bite, and you end up using more pedal pressure/travel to stop the car. They are very linear, the release characteristics are friendly, and the wear looked to be VERY good after a 2-driver weekend at CMP, which is tough on brakes.

This looks like a good option for track days, but this is not the time attack/late brake/stand the car on its nose brake pad.

Hey! Small world! Nice chatting with you guys!

We had a blast and her first time tracking the car was a great success. She managed a 1:48.7 Sunday afternoon which I'm super proud of.

Surprisingly 35-36psi hot seemed to be the sweet spot. I tried airing them down quite a bit for a session and ended much more understeery and ultimately slower. May be due to being 10mm wider than the stock tires and slightly bulged.

I'm impressed with their heat tolerance and wear, so they check all of the boxes! Also .6 quicker best to best vs the OEM tires but consistently over 1 sec quicker throughout the session vs the 1 or 2 hero laps you can get out of the PSS.
