I swapped my front shocks last winter from a set of single adjustable extension steel Koni coil overs to a set of Afco double adjustable aluminum coil overs with 350 Lb. rated springs. They didn't come with instruction on how to set the preload up on the coil over springs so I ended up setting them with no preload at all due them raising the front of the car up one inch with no preload on those springs shock The car has ran a new best 60 Ft. times that way this year with a 1.24 compared to a best of 1.27 ever with the Koni on it work
I'm in the middle of changing the springs to a set of 300 lb. rated Afco coil over springs and I am wondering if any of you drag racers have played with different amount of preload on the col overs or not on the front coil overs and if so what your thoughts are on doing this help
All comments welcomed up
