String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
The MMX Performance stud & nut conversion kit is one of our most popular upgrades. But when your car is left parked in a public location, the addition of our locking wheel nut kit is a must-have to help guard your wheels from theft.
Supplied as a set of X4 locking nuts plus the matched removal tool. Please note that the MMX stud & nut kit is not included. Compatible with both MMX stud lengths 70mm and 80mm.
Each kit comes with a removal tool with a security pattern that precisely matches the head pattern of each of the X4 locking bolts in your kit.
Install really couldn't be easier! Simply remove one of your MMX nuts from each wheel, and replace it with the locking version.
Each aluminium locking nut is finished in exactly the same gloss black anodised as your MMX nuts to match in perfectly. All BMWs with M14 x 1.25 MMX studs
