OEM Lemforder control arms, part # 31121127726 & 31121127725.
Bought from Turner Motorsport. Was on the car for ~500km in summer. I ended up going with 97+M3 arms for added caster. Nearly new. The boots are all in perfect condition. The white is from a coolant leak, but is not corroded, could be cleaned off.
Located in London, ON.
