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

Thats way too high for that size.

With zero camber? It's about right if one wants their tires to last until they get proper camber arms.

 

[Mash]

That’s what I thought any recomendation ?

Start from calculating nominal load pressure Tire Pressure Calculator

For the track measure inner, outer, center tire temperature. If outer is highest - not enough camber, if lowest - too much camber. If central is highest - too high pressure, if lowest - too low pressure.

For the street look at the shape and wearing signs. Also if its too bouncy - its too high. If its not holding potholes well - too low.

I also run lower pressures: 32 PSI cold on my 275/35R19 daily all-seasons, and have settled on 30 PSI hot for my Federal 595RS-pros, also in 275/35R19.

I daily and race with 3.2f and 2.4r camber.

I tried daily high front camber on 4s and cup 2 - not enough front grip and wears inner edge.

I disagree whether its stock camber or not. It's not a stock size tire.

I kinda want to see a pic of the sidewall of those RSRRs, after being run at 2.1bar/30psi with no camber.
I'd run 2.8-3.0bar until you get front/rear camber arms.

As you can see tire wear is pretty well distributed maybe a little more in the center

Thanks for these, but I was really wondering about the outer sidewall getting scrubbed too much. This one is showing the inner sidewall, which is predictably doing nothing.

Yup my bad ill upload a picture after tomorrows trackday

What are the California track day opportunities once I graduate from Tesla Corsa?
I am close to Willow Springs but the schedule of events is confusing to a newb.
Also is mixing with all types of vehicles hard to adjust to?

Stock Rotors only good enough with regen on I got out after only two 2 minute laps second Lap for cooling and brakes where red hot

 

[iridium]

So I had my M3P at the track this weekend and tried running without regen to see how it impacted battery temps. Well, the battery seemed fine, but in a few laps I got a warning that the brakes were too hot. I'm running the MPP BBK in the front and upgraded rotors in the rear with track pads all around. Do you think the warning is something to worry about? I wondered if the Tesla has some hardcoded brake temp warning. The brakes felt ok.

Also, scan my tesla said the front temps peaked at about 1200F.

The displayed brake temps are just an algorithm assessing average brake usage, and assumes stock brakes when presenting warnings.

I’d honestly say slowly work your way up to find the limit. As long as you are paying attention, fade should not develop so quickly as to be unsafe (I.e. everything is fine and then you go off the track in the next turn).

Very curious if you guys have had a chance to examine the new suspension on the Highland refresh which is of course more than a refresh. Wondering if the existing kits and various pieces including your fantastic front lower control arm bushing will fit the new models or whether you're coming out with a new ones next year.

The MPP homework on the Highland is already underway and we will either release updated parts for the new car or update our applications if the -2023 parts can be used!

I can now sprint for 3 laps in a row on a small track with a length of 2 km, and then the center pad shows an overheating alarm, but the brakes don't feel softer, can I assume that the brakes aren't really overheating? Is it harmful to keep pushing? At present, the brake fluid I use is SF650, and the brake rotors and brake pads have been replaced, and the original calipers are kept.

It’s likely the warning is mostly preventing drivers from boiling stock fluid first, and then slicking the stock pads second. Having replaced both, I think you are good to ignore the [electronic] warnings. I have not heard of anyone damaging the stock P calipers themselves from heat.

If you put a high temp fluid you might unlock a path to Blackbo.

Anyone ever run into this?
Added white line caster bushings and now I’m making contact with endlink on UP Sway bar in the front.
I know it’ll probably stop if I add more bar but the car doesn't need it in the front imo.

How old is your bar? Some early ones apparently rubbed even with stock caster.
This may be relevant.

UP Front Sway Bar Endlink Rubbing

Creating a new thread so we can stop hijacking everyone else's threads :) The Unplugged Performance front way bar, in the recommended "soft" setting, causes the sway bar end link to rub on the lower control arm, as seen here on my 2019 Model 3 Performance: Also reported by @webbah here Sway...
