The spit leafs are supposed to be IT. One rate in front one on the rear side. Honestly if I were building my car that way I would use a system that is designed to work together. If you got the money then yes that is exactly what I would do. Pretty much is what I did but with a road race suspension. Called the guy and said give it all to me.

 

cool I emailed caltracks, we'll see how bad the sticker shock is :-)

My goal is to run a legit high 10 second quarter mile

 

There prices are on the website. A little over a grand for all of it I'd guess.

 

Comp Engineering also sells a nice set of traction bars for under $400 that work very well:
