Pulley sizes are as follows:

E92 M3 VT1-550: 101mm
E92 M3 VT2-595: 99mm
E92 M3 VT2-625: 96.5mm
E92 M3 VT2-650: 98mm (custom 7-rib), with larger crank pulley.

The 650 uses a larger crank pulley to retain as much belt wrap as possible, eliminating slipping.

Your website now shows a 7-rib pulley option for the 625 kit. Does it use the same larger crank pulley as the 650 kit and does that affect the supercharger pulley size listed above?
