I doubt it. I think the 'M' cars all use the same set-up: the sway bar attaches to the strut, not the lower control arm like the ti. I have not checked under an M roadster lately, so I may be wrong.
I have the entire M3 front suspension, with the M3 front sway bar now. The M3 bar is actually smaller in diameter, because it's shorter. It mounts to the same point on the body, but the strut is totally different. |
