This kit includes wheel spacers which are 7mm thick and longer wheels which are 7mm longer than standard.
 
The spacers are intended for use with the standard Caterham 8" rear wheels when running slick tyres. Due to tyre flex in cornering we have experienced some cars suffering rub marks on the Watts linkage. This kit moves the wheel out 7mm to help reduce this and has been machined specifically to fit the Caterham hub.
 
The spacer features an internal recess on the back which fits over the original drive flange shape. It then has a outward collar to match the drive flange enabling the wheel to locate on the center.  It has 4 clearnace holes for the Ford stud pattern.
 
Fitting this kit requires removing the drive flange and brake disc for access to replace the wheel studs. 
 
The kit contains 2 wheel spacers and 8 wheel studs as per the picture
