BMR is the most popular Re-location brackets. Buy the weld in. B/c sooner or later you'll have to weld the bolt-on ones anyways, plus they are chaeper =)

LCA's. Lots of good brands, but i personally have the MAC's.

And they do compliment each other well, esp on a lowered car.
If u have a lowered car, you might want to pick up a PHR as well.
I have a MAC one too

I've had excellent results with the SPOHN PERFORMANCE LCA's, relocation brackets and adjustable torque arm.

The relocation brackets will help with a stock ride height car, particularly if you are putting down serious HP. I run them in the lowest mounting hole... insuring the axle end of the LCA stays below the body end when the body squats on a hard launch. Easy to move the LCA to either of the holes, to try different setting.

Pinion angle is typically adjusted to -2deg on a stock or bolt-on setup, to as much as -4deg with a big power adder. For extensive street use, you probably don't want to go more than -2deg.

The shocks are HAL/QA1 adjustable. The fronts are usually set at 1 or 2 at the track, 5 or 6 on the street. The rear shocks are usually set around 5 all the time.


The Spohn TA front mount bolts to the pads for the "g-load brace"... the thin sheetmetal piece that connects the two sides of the driveshaft tunnel, about a foot behind the tranny cross-member. This get the TA load off the tailshaft of the tranny, where is contributes to tearing the tranny mount when the TA lifts in response to torque at the rear axle.

Here's a picture of the Spohn front mount on the car... although that is an "early" design TA... his current design is the one linked above.
