20smoke run the mission as a 540. For all I know it could be yur old car as I got it 2nd (well maybe 3rd) hand.
SpongerX yes it's a bit weird. I think my first one may have been due to heat but I'm not 100% sure.
When I get a replacement rotor I may back it off slightly from 20smokes settings and creep up on it a little and check temps. I really don't know what happened with this one. I'll email tekin and see what they have to say about it. Don't want to have to replace rotors every 3 meets.
