Tires were 245/40/18 front abs 265/40/18 rear on 513M rims.

I found the 3Rs to be a bit "greasy" throughout the pressure range and they felt like a less precise RE71R. That being said, they are very progressive at losing grip and intuitive when they start allowing for time to correct as long as you're not overboard. I did 4 sessions each of the 2 days with total mileage around 190 over the 2 days. I think I have another day, maybe 2 at most on these. Looking at the wear pattern, I believe more camber would help these tires as you can see the outer edge wearing faster than the main tread face.

Overall, I am not so sure I would get these again. Will likely go back to SC3s once these are done, unless they turn out to be substantially quicker on my local track compared to the 3s.

Running these with small camber is just not wise. You are throwing away money basically by not using half of the tread. I do think supercar3 is a good tire for your application. Even though I ran sc3 with -3 camber..
