Heres another clutch question. I have a 89 gt with 450 fly wheel hp and am going to run drag radials. I was thinking of going with a centerforce df because they are great and would be perfect for my setup but I have heard that the counter weights will over expand after 6000 rpm. I was planning on revving the motor to 62-6400 rpm every once in a great while but am affaird of the weights over expanding and sticking. So I was wondering what some of you guys were running and your opoinins on this clutch and other. And if I should not even worry about the weights at all, or another clutch to look into. I have to drive the car everyday so it has to be streetable and barable. I know it is like wanting something that is impossible but I just need something like the centerforce.
