Hi Peter F, I use my RCF on the track and drive it as hard as I can. My last track day I completed over 220km and no issues what so ever. There are several RCF's running track days in Australia and the oil temp stays on normal or at worst 1 notch past. No one has any issues that I have been aware of. These cars are made to run hard and I will be running my next track day in a few weeks and again December when our temperature can be 25-30+.
