Bilstein does not make different front struts for the 318ti and 323ti. The Bilstein struts for a ti are also the same struts for a 328.

But here's the reason I'd hesitate to buy this set on Ebay:

Bilstein makes E36 shocks/struts in two flavors- Sport and HD. They are identical except that Sport is made for use with aftermarket lowering springs, and the HDs are for use with stock OEM (or other non-lowering) springs. The Ebay posting doesn't say which he's selling.

I have HDs on mine- nice, tight ride.
