The reason he gives, is that the wheel carriers are different ( 31216793923 vs 31212283435), therefore the suspension overall behaves differently (thus the different arm lengths). He told me, that when steering, the inner wheel would turn waaaaay too much compared to the outer wheel. This could be OK for drifting, but not race driving.

What do you guys think? Did you already hear that? Is this simply an alignment issue?
We first did the conversion back in 2008 on our E90 335iwhen the E9x M3 parts became available and have sold and install hundreds of these. Alignment is required after installation.
