Thanks Ron, I'll try 35* 1st trip to the track,hopefully in early April! Still need to purchase some slicks. The last set I bought off of Gary Jacob(Jake's Automotive)They were slightly used and he gave me a great deal on them! $100.00! They were Goodyear Eagle Radials. The GTX REALLY liked them! Very stable on the top end,too! If you know anyone selling slightly used one's,let me know! Cotton Candy flavor,eh.... that's what race gas smells like to me! LOVE that smell! Randy B
