I just posted this in another thread.... but the best bang for the buck suspension setup that is good for 1.6X 60 fts assuming you have 3.73's or better is:Remove the front sway bar
slicks
maybe weld up the control arm mounts if you plan to do this often and your car is 'heavy'.
Clutches, axels, trannies carriers, ect will need to be replaced and upgraded when they start failing.... but at least you didn't waste $$$$ on control arms, shocks, struts, springs, and drag radials to show up to the track and run 1.88 60 fts all day.
