Centring ring 68,1 x 56,6 mm

Plastic centring rings for aluminium wheels are used for stable mounting of the wheel on the brake disk hub. 
The centring rings avoid knocking and steering wheel vibrations at high speeds. 
Plastic material does not corrode. 

Dimension A (outer diameter) means the wheel hole diameter, dimension B (inner diameter) means the wheel hub diameter, and dimension C (cone overlap) means the length of the recess - see the picture. 

CAUTION! If you are requesting centring rings for all 4 wheels do not forget to verify that you have 4 pieces in your shopping basket.
