Working on a 67 Chevelle for a friend and thought I would reach out to my Buick friends for some schooling. Do you do any frame mods or bracing to the frame when building a 10 second car ( hypothetically) What would be a good suspension recipe and what spring part # work with these. Thanks in advance.
Great,you can go to town on it. Look at my topic in this section below,titled “Prepping my Frame.” That will give you some ideas about strengthening the frame with different supported and gussets.
My advice would be to go ahead and do a wilderides box, its overkill for 10's but when the urge to go faster comes he'll be better prepared for accomadating poor track conditions. Tie the lower lca mounts to the frame, as well as the frame to the rear crossmember. Double adjustable lca's, Solid pivot style Anti roll for a strip only car, HanR style bar for street driven stuff. Viking Shocks the Crusader series GLOBAL WEST arms for street/track TRZ arms for strip only Moog 5401 rear springs or go coil over Front springs lot of variables but try to get as much spring as possible in there ie height but smaller wire dia so it's got plenty of stored energy
Stock stuff with afco or GW bushings work really well also, but to be honest time you factor in the labor involved, the bushings and ball joints it's more cost effective to just buy new and move on with your life. Stock rear suspension has gone 1.30's but you gotta be on a great track and consistancy suffers regardless
