I think that your choice depends on what you plan to do with your car:
A lot of track >>> JRZ or KW Clubsport
A lot of road >>> KW DDC.
Would agree, the DDC are affectively V3's but the ability to adjust electronically, fine for the occasional track use, frequent track time go 3 way clubsports .....
Turner Motorsport seem to rate the DDC on their own M3
