When I built my car I wanted to build a sleeper so I went with high dollar Super Stock syle springs. I clamped them here there and every where but never got consistant results. I finally decided to try Caltracs. Thanks to Chip and others on here recomending them. I love the set up. The car hooks and consistant every pass. I didn't run my best 60 ft ever because of the heat and sorting out the car but it was right there.
The car hooks. I set them at home in my garage and only had to make shock adjustment at the track. The car launches straighter and I get less body twist.
The Caltracs may be a little stiffer on the street but it is barely noticable.
