Getting more confused the more research I do on the best way to lower my 70 GTO a little and improve the stance and handling.

Originally considered the 2" drop spindles included in the Right Stuff's 4 disc conversion, but have been advised against a corresponding 2" drop in the rear with driveline/pinion angle geometry. Some say can be fixed with adjustable rear upper control arms, others say 'no'. I've also been told that a 1" drop in the rear would not be an issue and would not require rear upper adjustable control arms.

Additionally, I've been cautioned against drop spindles (in general) and pointed in the direction of lowering springs for improved geometry. Is this a better plan? Had considered doing front upper/lower control arms (and possibly taller ball joints) either way.

Currently leaning toward this BMR kit (1" drop). It has non-adjustable rear upper control arms and still wondering if they need to be adjustable?. Might nix the sway bars (to save some $$), since the GTO has factory 1 1/8" front/rear (I believe).



So many questions...any guidance/experience would be greatly appreciated. Trying to do this on a budget to achieve the stance below using the same 18" wheels/tires ...would 1" lowering be enough?
