A lot of the extra weight in front on the Xi is unsprung. I.e. hubs, axles, outer CV joints, & heavier lower susp pieces, are not supported by the springs. FWIW I have had no bottoming problems, in fact fewer/none compared to stock which was terrible, even on non RFT Conti DWS. And weight wise my car is a pig, Xi + AT using the same Eibachs as non-Xi MT.

This fact still blows me away, that a much lower + stiffer "sportier" susp bottoms less and feels so much better on terrible roads. In fact I never would have believed it had I not previously put the same K/E susp on my other car (e36 M3) and it soaked up bumps like magic, far better than the stock 335Xi. So I thought WTH go for same set up on the Xi.
