Front End Unsprung Weight

I'm all for lowering the Roll Center but not when the LCA can barely move more than 1.5" before crashing into the frame. Not on a street car with sane wheel rates & a Stock LCA.

Several years ago, Firm feel adapted 73 B-Body LCA to FIX the pot hole = bent arm scenario but keep the lower RC. It adds a good 2.5" of travel over a stock LCA.
A more readily available & intermediate step would be a QA1 LCA, with its smaller dimensions offers ~3/4" of added travel over stock

If excessive stock Anti-Dive is unwarranted on upgraded B & E bodies, its certainly unneeded on an A-body. My modeling supports it and its #1 on list to test.
