Rear track width reduction kit

£250.00 (Incl. VAT)

This kit uses the BMW Z4 hubs to reduce the original Z3 rear track width by 20mm (on each side) to allow your wheels and tyres to sit inboard of the wheel arches. It fits all 6 cylinder cars.

The kit includes a pair of the following:

  • Z4 hub
  • Modified rear disc
  • Quality wheel bearing
  • Caliper spacer

The discs have been turned down to the correct diameter and the spacers apply the correct offset to the calipers to avoid a lot of fiddling and the prospect of issues further down the road.

If this is going to be a DIY job then you’ll need s BIG slide hammer and a bearing puller tool
