Race Tracking Your Supra - Information exchange

[Rocksandblues]

Speaking of your brakes thread, what’s the general take on Endless vs Torque vs SRF brake fluid?

Endless tastes the best out of the three.

Mine did the same on brand new rotors with zero previous compound on them. Have you seen my brake pad list thread here? A lot of other options, for a lot less money.

If it’s in this thread I may have missed it. I saw your positive review of the club racer pads somewhere in here…

SRF has the highest wet temp, if you don’t track much or the car sits longer. Otherwise, any of those DOT4 brands are great. Race teams will use whoever is their sponsor (free).

I was leaning towards SRF until I read a @razorlab post that said SRF didn’t feel good compared to the others.

I just switched from RBF to SRF and it got rid of my random soft pedal once the brakes get extra hot.

That's because RBF is trash.

Agree, which is why its now in the trash. Only reason I used it was cause I had a bottle left over and figured it was better than stock.

Personally I like 36 psi for a target hot pressure. Good to know I’m w/in limits ? running Maxxis RC-1 tires. If anyone else is interested ?



Discounted if a NASA member. If anyone else running a square 275/35-18 setup

Those recommendations are for a much lighter vehicle. Tire contact patch is proportional to vehicle weight divided by tire pressure.

if your Supra is 18% heavier than the spec e30 (or whatever) the manufacture will, as a general rule, recommend tire pressures 18% higher to maintain the same tire shape and contact patch.

Yessa. I don’t think they recommend a square setup either. But there is a huge range there if peeps check it hot. A pro buddy prefers the psi even lower. I love these tIres on our Supra ?

I run 275/35/18 and have used 3 sets of the maxxis. Hot temps I have tried 30 to 36 and ended up at 34 seeming to be the best. I have corded the out side fronts at about 4 track days even with different camber and pressures. So they tend to roll the edges more than some of the other tires. But they are up there with the fastest tire out side of slicks from my perspective.

Any of you run your own transponder like Mylaps TR2?

yes

yes

What's up with the subscription? Is it needed to record lap times or is it only for the app? The venue I go through has there own timing stuff which works with the Mylap stuff.
