These arms crashed into the body mounting brackets on my 2009 370Z. Stock rideheight and suspension. When the suspension compresses over a hard bump, the arm hits the steel bracket before the bump stops. This is dangerous, it puts bending/impact loads into the arm and could break the arm. SPC's half-baked solution is to "bend the metal out of the way" (https://conceptzperformance.com/items/37611/docs/40_file.pdf) for $700 arms this is unacceptable. Yes, my arms are on the correct side.

Do not buy these control arms, they have absolutely thrashed the mounting bracket with upwards travel. For a $700-$900 control arm this is not acceptable. SPC should be refunding anyone that bought these and paying for a shop to weld up a new mounting bracket. Looks like I’m not the only one this is happening to as well. CZP please stop selling these if you care about your customers. These control arms will cause severe damage to your car.
