I can't tell much from the tire temps he posted, for a few reasons. When were the temps taken? Straight off a hot lap or after a cooldown? Directly after getting to pits or was there time in between? How were the temps checked - with a probe or surface IR sensor?
Based on what is here, I can make general assumptions. Seems to me like this is a CW, primarily right hand turn course, so the LF is taking a lot of the load and the inside tires are cooling down. Either that or the final corner before coming off the track is a right hander.
Session 1 has no reasonable data to pull from since it's apparent the car wasn't driven as hard as the later sessions. Later sessions were better. Yes, there is a general trend that the outer edges are not as hot as the rest. Answer the above then we can come to a conclusion about camber, pressures, etc.
I would expect even more heat from the tires with a 250whp 86 on 245s. I would expect maybe 160-180 or so. I believe the RS4 optimal range is around 170? I know the Rival S 1.5 is 160.
