i ran 32-34. i have had stock, sp8000s, and azenis. works fine. i like 34 all around.. if u want more oversteer then drop it to 30 and raise the front a lil more.. but i think 34psi is pretty neutral. 50psi.. damn.

 

i think 50 psi is to much, i put about 35 psi in my tires, i put a little over 40 at one time but it created a small leak
