Trailing Arm Mounts Buyer’s Guide

These bolt in where the stock rear trailing arm mounts go, and are sold as a left and right pair with hardware. They come in two styles, Rally and Track. Both keep the stock mounting point and add a hole for our +2" trailing arms. Rally also adds a second set of holes for lifted cars.

Which one do I need?

Your car Pick
Stock height, with stock arms or our +2" arms Track, for more ground clearance. Choose Rally if you might lift the car later.
Lifted, with stock arms or our +2" arms Rally
Has, or will have, one of our T-Bars or a Geometry Special with its T-Bar Neither. Your T-Bar already comes with trailing arm mounts.

The two styles

Rally

Four holes give you a stock height and a lifted position for both stock arms and our +2" arms. The lifted holes sit 1" lower, so the mount hangs lower than the Track mount.

Track

Two holes, both at stock height: one for stock arms and one for our +2" arms. Without the lower holes, it sits higher than the Rally mount and gives more ground clearance.

Hole positions

"Forward" means toward the front of the car.

Hole Where it is Ride height Arms Rally Track
1 Stock trailing arm location Stock Stock Yes Yes
2 2" forward of hole 1 Stock Our +2" arms Yes Yes
3 1" lower than hole 1 and 0.5" back Lifted Stock Yes No
4 2" forward of hole 3 Lifted Our +2" arms Yes No

The +2" arms are 2" longer than stock, so they bolt in 2" further forward.

What they work with

Works with

  • Stock trailing arms
  • Our Trailing Arms, in stock length or Extended Length (+2")

You can also add these mounts when you order our Trailing Arms, using the Replacement Mounts option on that product.

Does not work with

Both T-Bars include their own trailing arm mounts, so you don't need these.

If you order the Geometry Special with Remove T-Bar, the trailing arm mounts go with the T-Bar. You'll need to make your own mounts or use these.

Fitment

A rear part for the GC/GD group:

  • Impreza / WRX / STI 1993-2007 (GC, GF, GM, GD, GG)
  • Legacy 1990-1999 (BC, BF, BJ, BD, BG, BK)
  • Outback 1995-1999 (BD, BG, BK)
  • Forester 1998-2008 (SF, SG)

The 2000-2004 Legacy and Outback (BE, BH) are not included, because only our GC/GD front parts fit them.

Common questions

Can I run stock arms now and switch to +2" arms later?
Yes. Both styles have a hole for each, so you only move the arm to the forward hole.

I'm at stock height now but plan to lift the car. Which should I get?
Rally. It has the stock height holes as well as the lifted ones.

Is it one mount or a pair?
A pair, left and right, with hardware.

Why choose Track over Rally on a stock-height car?
Ground clearance. Track doesn't have Rally's lower lifted holes, so it sits higher.

I already have one of your T-Bars. Do I need these?
No. Every TSSFAB T-Bar, including the one in the Geometry Special, comes with its own trailing arm mounts, and these mounts can't be used with it.

Do they work with your XXXL Trailing Arms?
No. They work with stock trailing arms and with our Trailing Arms in stock length or +2".

Can I get them powder coated?
Yes, as an option on the product page. Powder coating adds about 2-6 weeks. See Powder Coating.
