Adjustable LCA's
What is the purpose of adjustable control arms; and what length adjustment gives you the maximum benefit? If I was to use the Eibach Pro springs (1.3 drop) would I still need the relocation brackets or could I just change the length of the LCA's?
Someone please enlighten me.......

The "adjustable" feature only provides a couple of things:
1. Center the rear axle assembly front-to-back in the wheel well.
2. Move the axle front to back to maximize clearance for large tires, e.g. - 28" slicks.
3. Align rear axle assembly perfectly perpendicular to the longitudinal axis of the car = "thrust angle".... generally not a problem on a solid axle setup like the 3rd/4th Gens.
4. Compensate for slight rearward movement of rear axle assembly when you lower the car. If you work out the math, its not much.
The LCA relo brackets alter the LCA geometry, to keep the axle end of the LCA below the body end, and prevent wheel hop. You can't accomplish that simply with "adjustable" LCA's. You need the brackets.
