I'm not sure if you got my PM. I offered to buy a 330 steering knuckle and have it shipped to you to compare. Interested?

Now days you can literally google "e46 m3 (insert part name here)" and ECS Tuning will pop up as one of the first results, no part # needed to search! Love how well they've done their SEO |

Quick update: My 330 knuckle came in today. Took some quick measurements, and found that it appears to add ~1 degree of positive camber from the regular M3 knuckle. This means it has ~2 degrees more positive camber than the CSL knuckle. The non-M knuckle is a completely different casting from the M3 & CSL knuckles which only differ a little in the lower strut mount machining.
It also locates the steering tie rod ball joint a little closer to the LCA ball joint, so it quickens the steering ratio a bit.

Volke, thank you again for sharing this info.
How about the roll center? Is the ball joint further from the axle, vertically, on the M3 than the 330? I recently heard the ball joint taper was smaller on the 330 than the M3, can you confirm that.

I've always been a little curious about why BMW did things the way they did on the Z4M - wonder if you have any thoughts on the matter as a mechanical engineer.
Basically the Z4 non-M has the same steering knuckle as the E46 non-M. But the Z4M steering knuckle is fairly different from the E46 M3 knuckle. The shock bolts onto the knuckle (E36 style) rather than fitting through the ring like on the E46 / Z4 non-M (pictures below) ![]() ![]() Any thoughts as to why they'd essentially go back to an earlier design? Is there an advantage of one method over the other? |
