Fitment Note: These are rear lower control arms covering the GR/GH chassis WRX and STI (2008-2014) and the VA chassis WRX and STI (2015-2018). Installing these arms requires replacing your sway bar end links since the OEM links are not compatible with the new mounting geometry. BLOX specifically recommends Perrin or Kartboy end links as replacements. A wheel alignment is required after installation. Sold as a pair covering driver and passenger sides.
Specs and Features
- BLOX Racing rear lower control arms, sold as a pair
- Position: Rear
- Available in powder coat Black, Red, or Blue, select color from dropdown before ordering
- Multiple mounting locations for the rear knuckle, shock absorber, and sway bar end link for fine-tuned rear suspension geometry adjustment
- Allows rear camber correction on lowered vehicles where the factory suspension has gone beyond its adjustment range
- High quality steel construction with corrosion resistant powder coat finish
- OEM sway bar end links are not compatible, Perrin or Kartboy aftermarket end links required
- Wheel alignment required after installation
If you've lowered your WRX or STI more than an inch or so in the rear, the factory eccentric bolt has likely run out of adjustment range, which is what these arms are built to fix. The multiple mounting positions give your alignment shop the range they need to get rear camber back in spec on a seriously lowered car. Pick up the end links at the same time since you'll need them regardless.
Pairs well with:
- Perrin Rear Endlinks for Subaru WRX / WRX STi (2008-2020) This is not just a recommendation, it's a required purchase alongside these BLOX arms. The OEM end links won't work with this kit's mounting geometry, and Perrin is one of the two brands BLOX specifically names as compatible replacements. Order these at the same time so the install is complete in one shot.
OEM Part Numbers Cross Reference
- 20202AG010 (Rear Lower Control Arm, 2008-2014 Subaru WRX / WRX STI GR/GH)
- 20202VA010 (Rear Lower Control Arm, 2015-2018 Subaru WRX / WRX STI VA)
The OEM part numbers above are provided as reference for the factory rear lower control arms this BLOX kit replaces on the GR/GH and VA chassis WRX and STI. Confirm your specific factory part numbers using your VIN at a Subaru dealer if needed. This kit replaces both rear lower control arms as a matched pair.
Product Description
BLOX Racing’s rear LCAs feature multiple mounting locations for the rear knuckle, shock and sway bar end link. The design also allows for more rear camber adjustment for vehicles that have been lowered beyond that factory’s adjustment range and capabilities.
Rear lower control arms, which are manufactured from high quality steel, will come available in powder coated black, blue and red. Limited Series, special release finishes will soon follow after.
