MMR Stud and nut kit | BMW & MINI | 70mm ball seat

Remove and refit your wheels regularly? Then you’ll know how frustrating the factory wheel bolts can be: lining up the bolt holes, bashing your callipers with the wheel, trying to avoid cross-threading the bolts. All while balancing the weight of the wheel. 

The MMR Performance Stud & Nut Kit gives a stronger fixing method than using the original wheel bolts. Plus they’re a much quicker method to swap wheels for motorsport/track use as well. For all cars with M14x1.25 nuts - from BMW F&G-Series and Mini F56 onwards.

• Converting your car to our Stud & Nut Kit is a simple, reversible upgrade that will speed up your wheel changes.

• Our Stud & Nut Kit also allow for the safe use of different spacer size setups without the risk of running out of bolt threads.

• Beautiful midnight-black gloss anodised finish on the nuts will smarten up your car’s looks as well as its practicality.

• Both conical and ball seat lug nuts are available to suit either factory or aftermarket wheels.

• 70mm Stud:  No spacers, or up to 10mm spacer
• 80mm Stud:  Spacers between 10mm to 20mm

We also offer two different nut types, depending on what type of wheels you are running: Ball Seat nuts or Conical Seat nuts.

Please check which type your wheels require, it's important to get it right! Note that most OEM wheels use the Conical Seat nuts.

Stronger Fixing

M14 x 1.25 High Tensile Steel Motorsport Studs and larger anodised Wheel Nuts exceed the strength of the factory bolts for ultimate strength and safety.

Quick Wheel Changes

Stud and Nut kits are suited to any car that sees track use with regular wheel swaps. The studs really help to speed things up when you are trackside.

• As with all anodised finishes, do not clean these nuts with aggressive acidic or alkaline cleaners otherwise the finish will be damaged.​
• Use only pH balanced cleaners (ie, non-acid, non-alkaline, non-solvents). Never use ANY type of wheel cleaner or any chemicals including abrasive compounds on the nuts. We recommend washing with water and mild soap. We advise against using commercial carwashes who use aggressive chemicals such as TFR.
