Car is a BMW Z3, mild STR (Koni, springs, camber plates, exhaust).  Always 2 drivers and always hot (Florida).  I'll spray between runs, but wondering which is more heat tolerant - the Rival 1.5 or Bridgestone RE-71R?

Rival S.  RE71 doesn't really lose speed with heat but definitely loses feel while maintaining it's sudden breakaway character.  Makes it more difficult to drive.

 

Really only an issue in super hot sunny days with quick turnaround for runs (Prosolos, small events, challenges, etc)

Do you have camber plates on your BMW?  Even if you do the car is going to eat the front tires.  You can flip the RE-71's and have the same tread pattern. Not with the Rival's.

In Southern California we have hot, next to no humidity, I have driven both and prefer the Re-71's.
