no doubt it's all good
just think of it in this manner the car is going 70mph but the rx is enclosed & not getting any kind of circulation of cooling that is why certain drivers had that issue in off road of overheating the rx
another example drive 100mph in your car with no ac for 15 minutes an the temps outside are 90deg you would overheat as well

well the heat issue is easy to find out im sure someone has one of those venom heat probes u stick on your engine and gives u a constant heat reading just stick it in the rec box and run the car see how hot it gets..
but i still have to say the guys who have the problem got to recheck the cars something is touching might have to rebuild the whole car but guess it would b worth it

We were on the phone with mugen USA. The radio tray where the servos mount back to back you may want to use smaller screws. Like 3by10 mm. The longer 3 by12 mm may touch. This could cause some problems. I'm using 3 by 10 in this spot with the countersunk washers over the servo. Have no problems. Hope this helps.

Try a bit more rear toe-in. Also, move up the gurney strip on the body and/or move the body back.

I have run the car once so far on a hot day 95F. The rear end was unstable and unpredictable to say the least. I was running 35 all the way around and did not have time to do any testing.
I lowered the rear lower arms hinge pin to the bottom hole reset rear drop to 8mm, Changed the shim under the rear upper arm to 1mm, set front drop to 1mm and set the acerman adjustment to the middle mark. Car was good.
We have a race at the same track and I believe there are better answers for this track....
