Product details
Before fitment, please ensure the spacer fits flat to the back of the wheel. Please also test for clearance after fitment at the wheel arch under full right and left wheel lock.
These CNC machined precision alloy wheel spacers are 13mm thick with a 66.5mm bore and dual 5 stud bolt pattern for both 100 and 112mm PCD fitments. The spacers are anodised black to inhibit corrosion and "bonding" to the wheel or hub and are machined with an alloy spigot to allow centering on the hub. (often called "hubcentric" spacers) The spacers are suitable for most vehicles produced by Volkswagen Group. A 13mm spacer will give an overall track increase of 26mm when fitted to both sides of an axle.
