Megane 3 RS Stub Axle Spacer Kit
This kit spaces the stub axle out by 10mm per side using a waterjet cut aluminium spacer and a set of longer, high tensile bolts.
It is better to space the stub axle out rather than using wheel spacers as it reduces the loading on the wheel bearings.
This is a complete kit that includes everything you need:
2 x 10mm aluminium spacers
8 x M14 grade 12.9 bolts and washers
