After driving my BB Kit van for the last couple years and that of
another lister with them both front and rear, there is NO comparison
IMNSHO. ;-) I still have OE rears.

Easy to noitice the huge improvement when I first drove mine after
installation. The other van I drove is described by its owner as more
of an RV than VW van due to all the upgrades and mods, subsequently
how heavy it is.
I've never driven a vanagon that had such "normal-car" feel to the
brakes. High pedal brake-engagement, easy stopping response, balanced
stopping, no nose-diving. Admittedly he wasn't crazy about the
emergency brake marginal usefulness. He had an early iteration ('87
Jetta, I think) that were what was being used at the time.
