well went to the track on sat and could only get a 1.75-1.9 60ft on the new mt rad. i know it could have been track prep since others where complaining but i could not leave at more then 1psi or the tires would just spin. i tried 12-18psi in the tires with 15 giving me the best 60ft. my last gn used to have mt slicks and southside bars and i was able to get 1.5 with 0-1psi launches. i was going to go with them again "southside bars" but have been told by many that they are not the best way to go. anyone have any input? i am taking the front swaybar out today and plan on 90-10 shocks.
