Default Cusco Front Lower Arm Bar Type II Install & Review

Cusco Front Lower Arm Bar Type II
Part # 692 477 A


Install took about 25 minutes:
Use 17mm & 19mm impact sockets & a breaker bar or drive ratchet

I used this for guidance: https://legacygt.com/forums/showthre...56.html?t=5656

- Jack front of car & place jackstands
- Replace both triangular plates at the rear control arm bushing (2 bolts & 1 nut) with new ones and loosely install the two rear bolts.
- Remove both inboard control arm bolts (17mm), position the brace so it lines up with the bolt holes (and over the rear bushing studs).
- Reinstall the control arm bolts. Place a jack/jackstand/beefy arm under the control arm to help line up the bolt holes.
- Install control arm rear bushing nut, then tighten it and the 2 bolts down to approx. 100 lb/ft.
- Tighten inboard control arm bolts to approx. 80 lb/ft. I usually torque these down with the weight of the car on the wheels to prevent suspension binding.

Installed on 2009 WRX with:
245/40-19 Hankook Ventus V12 Evo 2 tires
2011 STI springs
Koni shocks
22/22 sway bars
2015 STI steering rack & Perrin steering damper lockout
SPC rear lower control arms
Rallitek adjustable rear endlinks
Rallitek adjustable rear toe arms

Front control arm rear bushing (ALK)
Steering rack
Rear subframe & differential
Rear trailing arm (front and rear)

The front end is more precise and direct with this brace installed. While coming in hot through a corner - especially when pitching the car sideways - I get a much more direct feel for where the tires are pointed and how much adhesion they have. I don***8217;t have to continually correct the steering angle (countersteer) while waiting for the chassis to ***8220;settle in***8221; under hard cornering. The subtle front end squirm under hard cornering is pretty much eliminated by this brace.
No additional NVH, just a more solid feel to the front wheels - great for a DD car. This brace paired with a 15+ STI steering rack makes the front end so much more precise. If you autocross or race, I highly recommend it.
