Yes,and yes.

We even recently released a new GM front coil over conversion that we`ve been working with Alston on for about a year now. It allows more jounce travel at lower ride heights than the previous package. In the rear you can use either QS2 double adj shock and the stock mounts or go to a G-Bar 4 link with QS2 coil overs. The DA adj. are great for dual purpose (street-road race/drag race) cars. For those who don`t need that much adj. the 16 setting QS1s still have a really wide adj. range, adj. both compression and rebound at the same time (most adj. shocks adj. only rebound) and they`re a lot more affordable.
