ADJUSTABLE LOWER CONTROL ARMS

TCA028, TCA029 – 2010-present Camaro, 2008-2009 Pontiac G8

RECOMMENDED TOOLS:

Hydraulic Jack and stands
Wrenches: 15mm, 18mm, 2x-21mm, 5mm Allen wrench
Sockets: 18mm socket, 21mm

INSTALLATION:

1. Lift vehicle and support with stands under the cradle.

2. Remove the rear wheels/tires.

3. On G8’s and 2010-2012 Camaros, remove the nut on the sway bar end links as shown in Image 1. Use a

15mm wrench and a 5mm Allen wrench. On 2013-newer Camaros with the FE4 suspension, remove the
end link using a 15mm wrench and 15mm socket.

4. Using a 18mm socket and 18mm wrench, remove the outer control arm bolt. (Image 2)

5. Using a 21mm wrench and 21mm socket, remove the shock cross-bolt. (Image 3)

6. Using (2) 21mm wrenches, remove the inner bolt. (Image 5)

7. Remove OE control arm. NOTE: while it is possible to remove the control arm at this point, it is

somewhat easier to loosen the (4) upper shock mounts. This allows the shock tension to be released and
the control arm comes out much easier.

8. If you are using BMR adjustable control arms (TCA029), adjust the control arm to the approximate

length of the OE control arm.

9. Install the BMR control arm and insert all of the appropriate bolts but do not tighten.

10. Load the rear suspension by lowering the car onto ramps or something similar that will allow access to

the control arm mounting bolts when the suspension is loaded.

11. If you are using BMR non-adjustable control arms (TCA028), skip this step and proceed to step 12.

Sighting the wheel/tire, adjust the inner control arm bolt until the wheel/tire is as vertical as possible.

12. Tighten the inner bolt to 85 ft/lbs.

13. Tighten the outer control arm bolt to 35 ft/lbs. Tighten the shock cross-bolt to 60 ft/lbs.

14. Re-install the end link and tighten the sway bar end link nut.

15. Using a hydraulic grease gun loaded with silicone grease, insert approximately 4-6 pumps into each

grease fitting.

16. Lower vehicle.

17. Take the car to a reputable alignment shop for a 4 wheel alignment. NOTE: with BMR adjustable

control arms, camber will now be adjusted using the large 1-1/8” adjuster on the control arm, NOT the
OE eccentric bolt.

BMR recommends the following alignment specs:

NOTE: Ride height and vehicle variance will dictate whether the above settings are attainable with non-adjustable control arms.

TCA028 control arms were designed to minimize excessive negative camber as a result of lowering the vehicle. If you track the
vehicle and want to run a lot of negative camber you will need more adjustability in the form of adjustable control arms (BMR Part
#TCA029)
