16 x stud and 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.

Please note, these are supplied as singles to allow you to mix sizes, front and back, if required.

A good quality thread lock must be used when installing these. We recommend Loctite 270, 271, 2700 or 2701, available to buy here.

Open ended wheel nuts are also required.

Length - Hub/Threaded/End
75mm - 15mm/47mm/13mm
82mm - 15mm/54mm/13mm
90mm - 15mm/62mm/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.

Please note that late R53 cars require the R56 size studs, so require the bigger nuts. Please contact us to confirm this.
