These arms allow for adjustment of camber in the rear of the vehicle. This is essential for lowered vehicles or race prepared vehicles. The mounting positions allow for a configuration which will not lower the vehicle. There is also an additional hole which will result in a drop of 15-20mm.

  1. I wanted camber adjustment, not a drop

    By Kian September 4, 2017

    These control arms have a nice paint job but I have 2 problems with them. First, you CANNOT use the factory bolts ('17 STI) connecting the arm to the wheel hub. These arms are wider than stock which makes it not possible for the OEM nut to thread completely onto the bolt. Took me about 3-4 days of asking around and borrowing people's cars to find a store that has the correct Grade 10.9 M12x1.75 80mm flanged bolt. Should've called the stores first I guess. Second, I don't like how much the car is lowered with these arms, even when using the regular wheel hub bolt location (bottom hole). I have RCE Yellow springs on my '17 STI, so it's even easier to notice that the rear of the car is about 10-15mm lower than the front. Can confirm that the front and rear are the same height with the OEM control arms. This is the main reason I don't like these RS*R arms. Additionally, the box these come in say that they are for BRZ and FR-S. The manual also says the same thing. I wonder if that causes the issues I have, even though the part number of the arms I received are correct. Overall I am not satisfied with this product. I recommend buying ISC control arms instead. They are cheaper as well as more reputable, and I don't see any advantage that these RS*R's might have over them.

    have had these installed for about 6 months now, quality and precision of these lca's are on point. love the extra drop it provides and wide range of adjustment. definitely worth the buy when wanting to change your suspension / alignment.
