For competition cars only. Not homologated for use on public roads.


On the BMW Z4 M E86 a 15 mm spacer moves each wheel 15 mm outwards: the track width of the axle grows by 30 mm and the effective wheel offset (ET) drops by 15 mm. The standard bolt is then too short. The kit comes with the 45 mm bolts, so you do not have to work out the length yourself.

For competition cars onlyThis product is not homologated for use on public roads. It is fitted to competition cars used on circuit, in rally or in drift.

What to check when fitting
  • With the 15 mm spacer fitted, a 45 mm bolt still engages 30 mm of thread in the hub.
  • The conical seat has to match the wheel, not the car. An aftermarket wheel may need a different seat.
  • Re-torque the wheel bolts after the first few kilometres.
