it uses mustang 2 spindles, and after the drag brakes and the few little things i wanna say 2800 bux, but i dont remember the prices on everything off the top of my head.. get ahold of denny he will be able to answer any questions you have about it.. to me its 100% worth the money not only for the tire and engine bay room but most importantly the saftey at 170 mph vs the sloppy old stock stuff..
