altercation vs hemi denny

I'll have my Alterkation this Friday. Bill told me that the track width is determined by the disc brake setup you decide to go with. He sells Wilwood... One kit he sells moves the stock track width out by 3/8". The other he sells, moves the stock track width IN by 3/8". I liked that his kit came totally complete, and I didn't have to add anything to it, other than brakes. I wanted it for the extra room, mostly. But I liked the idea of having a manual rack as well as coil over tuning.... Which you can obviously get from either system.
