Hey Guys:
I am restoring my 66 GTO and upgrading the suspension. I am looking at tubular A arms but am confused with some of the choices. Global West has one system with Negative Roll Geometry and a second with Standard Geometry. Which is best? I am not into drag racing, just want a nice show/driver. I want to lower the front end 1-2 inches, use 12 or 13 inch disc brakes up front, probably use headers too. They also have options for using coilover shocks or standard shocks---again is there any clear advantage to either one? Your expertise would really help, as this will not be a cheap setup and I want to do it right.

Thanks
George

The negative-roll conversion keeps the outside front tire from turning under (leaning outward at the top) during cornering like a factory A-body tends to do. Instead, it keeps the outside tire more upright, maybe leaning slightly inward, in order to keep the tire contact patch where it needs to be for better cornering.

George, Keep the stock uppers, add Moog off set shafts for more postive caster and the Ram Air Restoration CCK-1 GM Camber Correction Kit..

No Poly bushings only rubber...
