Gen 1 & Gen 2 & Gen 3 Mini Stud Conversion Kit



Gen 1 R50 R52 R53 JCW early models

M12 x 1.5mm   68mm   75mm  82mm 

Gen 1 R50 R52 R53 JCW later models

M14 x 1.25mm   68mm   75mm  82mm

Please note that late, but not all, R53 cars require the R56 size studs, so require the bigger nuts. Please check your car by removing and measuring a wheel bolt - it will either be M12 (12mm) or M14 (14mm).

Gen 2 R56 R57 R58 R59    

M14 x 1.25mm   68mm   75mm  82mm

This kit contains 16 x replacement conversion studs and 16 x  Black open ended 60 degree wheel nuts to convert your Mini from bolts to studs.

These screw into your hub with an allen-key. Essential in saving time for track use when regularly removing wheels, or for general ease of maintenance. All studs are made from 10.9 steel.

A good quality thread lock must be used when installing these. We recommend Loctite 270, 271. 

The Hub Length is 13mm

Open ended wheel nuts are also required.

Length - Hub/Threaded/End
68mm - 15mm/40mm/13mm
75mm - 15mm/47mm/13mm
82mm - 15mm/54mm/13mm

The thickness of the brake disc and wheel is approx 20mm. Subtract this from the threaded length of the stud to determine the amount left for spacers and nuts. Note that the end of the studs are unthreaded.

Please note the black nuts are not "show quality", due to the painted / powder-coated finish, and how they are packaged from the manufacturer. Chips and blemishes may be present.

Gen 3 Mini - all F series

M14 x 1.25mm   68mm   75mm  82mm

As above but 20 x studs and nut required

    Car modification laws in the UK and elsewhere are in place to ensure drivers who want to enhance their vehicles adhere to certain safety standards. While modifications are a great way to alter the look and performance of a car, some may also affect the handling and overall safety of the vehicle on the road.

    You may need to inform your insurance company of any modifications made to your car – whether they were already installed when you purchased the vehicle or if you have done them yourself. If you don’t tell your insurer, any future claim you make could be turned down. Worse still, your insurance could be completely invalidated. Modifications carried out to any car may affect the vehicle manufacturers warranty.
