Opinions: Fast-ratio manual steering, suspension upgrades
I have a 66 Formula S 4 speed Barracuda. Factory .875 torsion bars and front sway bar, Bilstein shocks, Firm Feel 16:1 manual box, HD 6 leaf rear springs, 15 x 6 rims with 60 series tires. I am running all Moog rubber bushings and the caster is about +2*. It is a very nice handling and riding car. Early A's feel lighter than later A's. The 20:1 box would be a nice compromise. Ride is very subjective, you need to decide that for yourself.
