No there was only one V1 part number for all Xi's. It is in the KW online catalog. If you look at other manuf. springs for 328 vs 335 they are usually different pn's, so I think KW just assumes the adjustable ride height feature can compensate for different weights. After all main (traditional) use of coil-overs is to precisely corner weight a car, not so much to make it look slammed though many just want that.

As for the bump stops they are there to prevent expensive metal parts from smashing into each other at high speeds when the suspension bottoms out.
