MASTER THREAD: Comprehensive Road-Course Modification Guide — Optimizing the 3 for the track

Pads can glaze with any type of rotor - slots, J hooks, holes etc. don't guarantee it won't happen.
The same goes for noise. There can always be some noise and even a feel through the pedal with anything other than a plain rotor.

I can't imagine glazing on my RB rotors, they cut like blades. But I'm more interested if anyone with RB rotors had really loud low frequency noise that increases with brake pressure. I will post a video later here - I'm starting to think that is not normal...

 

[destructure00]

Yes, I've had that noise too. It's like a grinding noise.

I went back to the track yesterday, the problem was better, but still a very inconsistent pedal. It didn’t get quite as soft as before, but still got softer over time. Since I am on a mini break before my next run, will try different pads too

Maybe your calipers got unbolted or rubber hoses overheated and lost rigidity - that usually happens with them if you boil brake fluid.

 

[mattack4000]

I will check the caliper bolt, the rubber hose theory is certainly plausible.

On my Evo Brembo I ended up finding that I've destroyed master cylinder and overheated calipers to the level that aluminum became softer. Eventually I had to switch to Stoptech calipers and those were rock solid. But it's cheaper to check calipers torque and change hoses to teflon (stainless) first.

Will a 18 x 9.5 ET30 with 275/35-18 fit under the fenders without camber plates, with stock Performance suspension?

I bought some federal race tires and Martian Wheels want to make sure I don't have clearance problems. I know about the wheel speed sensor that needs to be tied back, and secured.

That's a strange choice. 18? It's whole inch smaller than stock. 3.4% lower speed. That asks for 275 40...

18" = lighter rims, and a wider choice of race rubber.

3.4% lower top speed, no worries I'll take it. @TexasTeslaRacing is running this size I believe for autocross tires

It should fit. Ok, 3.4% more torque.

yes Hoosier A7’s 285/30/18. Works great. Keeps the costs down.

For the track I try to use a taller tire. 275/35/19

Do you think i will fit the 275/35 in without any camber plates in the front on stock performance suspension?

Yes they will fit, no problem. I fit 275/35/19 Toyo R888R without camber, coilovers and spacers.

Great thanks for that, I think it will rip on the track, and the P3D will never be that high speed monster anyway. Might as well play to the strengths of the car.

I plan on doing the Coilovers, and other suspension mods all at once, but I don't quite want to pull those funds out of TSLA right now.

I was hoping to just slap the new sticky rubber and Martian wheels on the stock suspension and enjoy a few track days in the meantime. Other than pads and fluid its bone stock, managed 1:50 at Laguna on my first event there.

I spun out badly, because I left the track mode on Drift Preset. (Opera Singer) Mis-TAAAAKE! I managed to do a 720 on the final corner lol! It was my first time on track since they opened up track mode to the sliders, wow.

If you want to learn, get some rs4s and a set of 18s. You will have a lot of fun. If you want 19s, I will sell my set after September as I go back to 18s. A stock p3d with good street tires and brake pads can hit 40, maybe 38-39 with a pro at Laguna.

I got a set of camber arms, didn’t make me go faster yet but I did notice bunch better wear on the tires.

Here are two new tip.
1. Do not f-ing use hub centric ring, more trouble than it’s worth and have fun removing it

2. 18x9 with 40 offset and 265/40/18 resulted in slight rubbing, maybe bring the tire out With a 5mm spacer

File slots in the rings so you can pry them off with a screwdriver and use some high temp copper grease on them

Why are you using +40 offset? Surely +35 would have been better?

Hmm, I've had no issues with my plastic or metal hubcentric rings. I'll admit they are a bit of a pain though.

18x9.5 ET 40 with 275/40/18 I NEEDED to use a 5mm spacer. Otherwise I would definitely be rubbing lol

 

[Dangerous Fish]

This is how they can end up, but it probably depends on the climate how quickly they go like that.
