Hi im currently looking for some lower control arms i want to go with spohn i plan on eventually getting some lowering springs (eibach pro or sportline) so was wondering if i need to have adj control arms or if solid ones will work also do i need to get relocation brackets? Thanks

 

If you plan to use the factory diff housing and your car is straight, non adjustables are great. UMI makes nice trailing arms and relo's!

 

same rearend housing yes and as long as the gears are posi they will be used as well otherwise ill grab a posi unit out of a donor rearend i know ill need a torque arm as well because im going with a t56, will or should that be adj?

 

Reallocation brackets move your mounting point for the LCA to Rearend down. This will help if you have excessive wheel hop on hard launches. I did when I first bought my car the brackets solved it. It will also help on a lowered car because lowering a car lowers the body not the rearend. So at that point your front (body) attachment for the lca could be 1" to 2" lower than normal while the rear attachment did not move. This can lead to issue if the front mount drops below the rear mount. This more than likely will lead to wheel hopping and traction loss.

Adjustable LCAs allow you to shorten the distance between the front and rear mounting points. This can be used to center your tires in the wheel wells. It can be handy if you have a lowered car, different tires that you want to get clearance for, or a rear swap. That being said with adjustable LCAs you need to check them from time to time to make sure the adjustor in the middle aren't getting loose. I've had the adjuster work itself loose over the span of a few years. I caught it during a Spring once over check before putting insurance back on the car so all was well.
