Leaf spring old school

[Rod]

Trying to improve leaf spring geometry on 68 Camaro. I'm machining new front cups to allow about .8" move outboard per side; with the 1 1/2" per side move inboard at back, this will keep springs more parallel and flat with centerline of car.

the triangulation on the rear leafs helps turn in on the car and stright line tracking for higher speeds, and helps with lateral location for the axle, you should leave it there, Parallel leaf springs really are not Parallel in the car,....dont take the name so Literal
