So i have some of the BMR adjustable lca's on order. My car has the eibach sportline springs so do you guys think i need to order the lca relocation brackets as well or will it be fine without them?

 

Hello, thanks for your purchase. To get optimum traction your lower control arm angle does need to be correct. If you lower your vehicle it throws the angle off. If you have any questions please give me a call.

Will they help? - sure

Are they needed? - nope.

 

Are they needed? I agree that's usually a no. They have their uses but are in no way, shape, or form required for handling.

If you have wheelhop, then it might be time to consider some, but generally lowering these cars helps hop, doesn't make it worse.
