This guy has some interesting options. Watched a few videos
Forgot to add...
The vz2 I was loaned for 2 weeks, was positively dangerous braking! Maybe it had glazed discs? Also the vz2 I test drove with 4k miles, braked terribly. Few crashes almost at roundabouts.
The vz3 I have now on the other hand is razor sharp precise as hell. Super fine control on braking. Can throw passengers at the windscreen at low speeds !!
Certainly worth the extra, not to mention how much better the matrix lights are even on dipped beam. Suspension also send much improved compared to 2 vz2s, Don't know why?
Only issue, you don't get a space saver on vz3 because of brevis, the foam to add one cost 80 £. And I'll need to swap back with front wheels then put space saver on the back if and when front alloy cracks on me (had a few go!!)
But
Totally worth it imho.
Zimmerman's I had on Audi before, really good. I've seen vz5 kits, try de forum of watch the videos of person I linked.
