Clamping the front of the springs?

Sorry guys, I disagree. If he's only gonna run it a couple of times at the strip, I would stay with the XHD springs. IMHO the SS springs are gonna ride too rough on the street. Plus you get the notorious lean which is fine on a race car, but awkward looking on a street car.

I plan on putting the same amount of horsepower down with 325/50 drag radials and am using the six leaf ESPO springs. They are pretty stiff, but not unbearable. If I have traction issues, I'm going to add Cal-trac bars.
