I used all of they're products on my A-Body (Tubular upper and lower control arms, Tubular Trailing arms, Front and Rear Disk brakes and booster/master cylinder, 2 in drop spindles and 3 in rear lowering spings) I also bought QA-1 coil over adjustables and Hotchkis sway bars. All at a very affordable price being that the aftermarket for suspension can be very expensive.
My Chevelle handles like my 09 Lexus is350 and stops almost as well.
They're products may not be for you and im sure everyone on this site has an opinion on what the "best" is but if you lookin for quality and affordability this is your place.
Ask Jason at Gearhead Garage. He said my car "drives way better than he expected" LOL
Ill take that as a compliment.
Good luck with your project.
P.S. look for the classic performance parts ebay store for a lil' better price than they're website
