I'm trying to stick in my class so haven't gone to a bigger size, might try 255 all around if I can work the balance out (right now it would probably make the car tail happy again) I'm hoping to pick up some used RA-1's in the current sizes, I think it would help pickup a lot of time.
For auto-x I run 235/255 on 17x9 and 10. I really like the wheel width to tire width ratio, makes the car easy to rotate and transitions very quick compared to the same size tires with 17x8&9 on my S-03 Bridgestones (street/track)
I'm hesitant to put too big of a tire since the Supra being heavy needs the transition help. I think a 255/275 on a big wheel would be nice though (10.5-11) but those are harder to find.
