The selected option (Japan Racing JRWS2) is ready to ship.


On the BMW Z4 Z4M a 10 mm spacer pushes the wheel out level with the arch, and the standard bolt is then too short. The kit comes with the 40 mm bolts, so you do not have to work out the length yourself.

Not compatible with the rear axle on BMWOn BMW the hub lip at the rear protrudes further than at the front, so a 10 mm spacer ends up sitting on the lip instead of seating flat against the hub face. The wheel is then neither hub centric nor properly clamped. For the rear axle choose the 20 mm set. On the front axle, measure how far the hub lip protrudes first: the spacer has to be thicker than that.

What's in the kit

  • 2 hub centric spacers, 10 mm thick, that locate on the hub lip. You choose the spacer brand from the list: Let's Race or Japan Racing JRWS2.
  • 10 Let's Race M12x1.5 wheel bolts with a conical seat, 40 mm long.

What to check when fitting
  • With the 10 mm spacer fitted, a 40 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.
