Not Ranked
The upper ball joint on our car does fall behind the lower, otherwise we would have negative caster. The direction that the bracket points is not critical, only the relationship between three points, the upper and lower ball joints and the tie rod outer end. If the two ball joints are in the correct orientaion, the only thing left to worry about is the tie rod end and it relationship with the rack. If the spindle is tilted back raising the tie rod and the rack was left in its original location you could have severe bump steer, however our chassis does not leave the rack in the stock location. With SN95 spindles the bump steer on our car is very close to zero, with older spindles there is some however not enough for most people to notice on a street car. Our race cars come with an adjustable set-up. Using different spindles may work, but the geometry should be checked first for bump steer, camber gain, and roll center height.
