Which springs would be better for drag racing stock rear springs or pro kit in the rear . I have Hal shocks and springs up front . Hal and pro kit in the back , but I don't like the way they feel in the back kinda stiff . Anyone have experience with both ?

anyone!

 

Eibach Pro Kit springs are not for drag racing.

But I a few folks who run them and their 60 ft times don't seem to be affected that much.

I have the pro kit rears in now . I was wondering if I should put the stock springs back in to get a better launch over the pro kit ?

 

I use the Eibach drag launch springs.

I'm pulling 1.6's with my pro-kit. I'm going to switch over to some V6 springs and see if I can get in the 1.5's.

 

Good question posted above... what do the drag springs do to the height of the car?
