lower control arm relocation brackets
 

Which holes on the relocation brackets are everyone using? I bought the bmr bolt in ones, they have two mounting holes. I lowered my car with eibach sprotines springs. The dirrections that came with the brackets din't help at all. Right now I'm using the lower set of holes. Right now the car doesn't hook up that well at all. Could using the wrong holes case that much of a difference?

When the car is at normal ride height (Not jacked up off the ground) you want the rear control arms to be close to paralell to the ground with the back mount slightly lower.

Consider that when you get on the gas, the rear of the car will squat. Now every car is different as to how much it will squat based on how soft or stiff you suspension is. Just keep in mind that under hard excelleration that at no time should the rear LCA mounts be higher than the front or wheel hop will result.

So basically the softer the suspension- the lower the rear LCA's sould be mounted in the relocation brackets to assure they do not go above paralell. As close to paralell under thrust will give you the best launches.

I couldn't have said it any better.
