Description
Bimecc BMW wheel stud and copper-coated nut conversion kit for compatible BMW E, F and G Series cars, BMW M models and the Toyota A90/A91 GR Supra. This 20-stud, 20-nut conversion makes repeated wheel changes easier and allows you to choose stud lengths independently for the front and rear axles.
Instead of locating wheel bolts while supporting a heavy wheel, offer the wheel onto the fitted studs and secure it with distinctive copper-coated open-ended nuts. Designed for road, fast-road and track-day applications with correctly matched hubs and wheels.
Choose the correct BMW thread
- BMW E Series: M12×1.5 for compatible E-chassis models including E46 and E9X platforms.
- BMW F & G Series, Toyota A90/A91 GR Supra: M14×1.25 for compatible F-chassis, G-chassis and Mk5 Supra platforms.
Do not order by chassis generation alone: confirm your hub thread pitch and wheel nut seating profile before ordering, especially on models with non-standard hubs or wheels.
Included in the copper nut kit
- 20 Bimecc steel wheel studs: 10 front and 10 rear
- 20 Bimecc copper-coated open-ended wheel nuts
- 60° conical-seat wheel nuts with 19mm hex fitting
- Choice of 68mm, 75mm, 82mm or 90mm stud lengths for each axle
Note: Copper describes the nut coating/finish. Studs are steel, not copper. This kit does not include a thread chaser, threadlocker, wheel spacers or fitting tools.
Wheel stud length guide
| Stud length | Typical starting-point use |
|---|---|
| 68mm | Standard wheel mounting without a spacer |
| 75mm | No spacer or some setups using up to approximately 12mm spacers |
| 82mm | Some setups using up to approximately 19mm spacers |
| 90mm | Some setups using up to approximately 27mm spacers |
Spacer limits are indicative only. The correct stud depends on wheel mounting-face thickness, spacer width, hub engagement and nut thread engagement. Verify these dimensions on the vehicle before driving.
Benefits for track-day and performance BMW owners
- Quicker tyre and wheel changes at a track day
- Studs guide wheels onto the hub during installation
- Separate front/rear length options for different wheel and spacer setups
- Distinctive copper-plated nut finish with black wheel studs
- Open-ended nuts make stud protrusion easier to inspect
Fitment and installation safety
These wheel nuts use a 60° conical seat. Match the nut seat exactly to the wheel: do not fit a conical nut to a ball-seat/radius-seat or other incompatible wheel. Professional installation is recommended. Clean and inspect the hub threads, follow the correct Bimecc fitting and threadlocking procedure, do not allow studs to bottom out, and torque the wheel nuts to the correct wheel/vehicle specification. Re-check torque after initial use and track sessions.
Need installation guidance? See our wheel stud conversion fitting guide. We also offer a BMW standard black-nut kit with installation tools or a BMW standard black-nut kit. For a VW/Audi/SEAT/Škoda, choose the VAG copper-nut M14×1.5 kit.
Frequently asked questions
Are the wheel nuts made from solid copper?
No. The wheel nuts have a copper-coated finish, paired with steel wheel studs.
Which thread size does my BMW need?
Many E Series models use M12×1.5; many F and G Series models and the Mk5 Supra use M14×1.25. Confirm your exact hub specification before ordering.
Can I use the kit with wheel spacers?
Yes, where the stud length, nut seating and thread engagement are suitable. Choose the lengths for your specific front and rear spacer setup.
Does the copper kit include fitting tools or Loctite?
No. Tools, consumables and spacers are sold separately.
Do conical nuts suit any BMW wheel?
No. Check that the wheel requires a 60° conical seat and has adequate clearance and thread engagement.

Wheel Spacer Questions Answered
Wheel spacers are one of the simplest ways to improve the stance, fitment and overall look of your car, but it’s important to choose the right size and type for your setup. Below, we’ve answered some of the most common questions we get about wheel spacers, including fitment, safety, handling, bolt length and whether they’re suitable for daily or track use.
Are wheel spacers safe?
Yes, when they’re fitted correctly. We always recommend using quality hub-centric spacers, the correct bolt length, and making sure everything is torqued properly. Cheap universal spacers or incorrect hardware are where people usually run into problems.
What size wheel spacers do I need?
It depends on the car, wheel size, offset and how aggressive you want the fitment to look. As a general rule, we suggest measuring the gap between the wheel and the arch first, rather than guessing. If you’re unsure, send us your car details and wheel specs and we’ll help point you in the right direction or checkout our guide here
Will wheel spacers affect the way my car drives?
A small spacer setup usually won’t cause any major issues, and many customers fit them purely to improve stance. Larger spacers can change the track width and steering feel slightly, so it’s worth choosing a sensible size for your setup.
Do I need longer wheel bolts with spacers?
In most cases, yes. If you’re fitting slip-on spacers, you’ll normally need longer bolts to match the spacer thickness. For bolt-on spacers, the spacer bolts to the hub first, then the wheel bolts to the spacer. Either way, the correct hardware is essential.
Can I use Bimecc wheel spacers on track?
Yes, provided they’re high-quality, hub-centric spacers and fitted correctly. For track use, we’d always recommend checking torque before and after sessions, and avoiding overly aggressive spacer sizes that could create rubbing or unnecessary load.
Will Bimecc wheel spacers make my wheels rub?
They can if the spacer size is too aggressive. Rubbing depends on ride height, tyre size, wheel offset and suspension setup. We always recommend checking clearance properly, especially if the car is lowered or running wider tyres.
