My co-driver finally bought himself a toy of his own to flog around the courses, and I am trying to help him with the best set-up possible. He ended up getting an 04 MR2 Spyder. Now, from what ive been able to find, the 195/50 x 15 tires were the special sauce tires formerly. With the R1R's now coming in 200TW, are the new 195/55 x 15 tires now the ones to have, or is the jury still out? Will these need to be/should be shaved?
