stiff or soft sidewalls
im looking for experiences with either stiff or soft sidewall slicks. i have a 2700 lbs, m/s 4 link 67 camaro, last year i ran 15x33 hoosier softwall slicks. i ran a 555, toilet on alky, and a glide w/1.80 1st gear. since i run only 1/8th mile i have had 4.86 in the rear. my best 60 ft was 1.15. this year i am building a 632, same car setup,probably 200more hp. was wondering if stiff sidewall M/T slicks would be a good thing to try. sometimes i get some shake and seems to roll the tires up.i also think i may have to back off the gear ratio a bit even though i still intend to shift at 7000. ran 14x32 stiff M/T back when the car was ladder bar and liked them then. thanks for your input
