I put Bilstein street valving on both my 68 convertible and the 65 Fastback I am working on. Absolutely love them. Yes they cost a fair bit more then the cheap crap, but they are worth every penny and compared to most mods they are still cheap.
The 68 vert wallowed and drove like crap with it likely original suspension. All is perfect done so is the shocks, Monte Carlo bar and export brace. Just those changes made a world of difference. The drive is smooth and it glides over bumps.
The 65 got the full treatment. GT springs all around, bilsteins, Arning drop, new control arms (open tracker Blue printed uppers) GT sway bar, ZRay crossmember, MC bar, export brace, and welded in the shock tower supports. Also rebuilt steering box from Chock, complete new steering parts with roller idler, and original style Disk brakes from Chock.
The car drives smooth and firm but comfortable. Cornering is a joy. It still belongs to the original owner, and he was blown away by how good it drives. Far better than ever before.
