Normal
I use my tongue. It was hot. :tongue:BTW: I measure rotor and tire surface temps at the track. Never measured the rim temps, but suffice it to say, the heat from the brake calipers and rotors do heat the rims. I would guess on "normal" driving the rear might get warmer than the front as we do have a 40/60 weight balance and if you are not on them hard like the track, the rear might get slightly warmer than the front. Now on the track you are looking at hot front rotors (480/280). I was at a HPDE where someone had an off into the grass and stopped there to wait for the track to clear before getting back on....dry grass caught on fire from either the hot rotors or cats/exhaust.
