The ST Trackparts wheel studs conversion kit allows you to run spacers of different thicknesses without changing wheel bolts every time. In addition to that it makes removing and installing wheels much easier!
The kit is built for motorsport using high quality 10.9 grade steel. But of course you can also safely use it on the street. We designed our wheel nuts such that the socket wrench will not touch your wheel, this makes it ideal for fast wheel changes without damaging your wheels.
We provide two different lengths, 75mm and 90mm. The 75mm studs allows for spacers up to 15mm and the 90mm studs allow for spacers up to 30mm.
There are two options for finish, the black version for an OEM look, or the copper plated version which provides more corrosion resistance and better durability.
The studs can be installed with an allen key.
The kit includes:
- 20 Wheel studs (75mm or 90mm)
- 20 Wheel nuts (optionally copper plated).
- Loctite
