..... I think I already know the answer, but I'm after a sanity check: I believe it braces the two front wishbones together. Hypothetically, if this piece were missing from an R26, would you imagine that it could explain a nasty knocking noise when entering a roundabout (i.e. turning right) in a mildly spirited manner?
More important, that fixes the 'carrot' bushes from the subframe to the chassis. Without it, you expect the whole subframe to move A LOT. Sent from my E6653 using Tapatalk
