Racingline Radius Seat Wheel Nut (Single)
The Racingline Radius Seat Wheel Nut is a single replacement nut designed to work with Racingline’s stud conversion kits. Sold individually, it’s the ideal choice if you’ve misplaced a nut, need a spare for the toolkit, or simply want to keep a few on hand.
Manufactured to Racingline’s usual high standards, this nut uses a radius (ball) seat, which is the curved seating profile found on most OEM VW, Audi, SEAT and Skoda wheels. The matching shape between the nut and the wheel ensures the wheel is centred properly and clamped evenly, which is essential for safe, vibration-free running.
Why choose this wheel nut?
- Direct replacement or spare for Racingline stud and nut conversion kits
- Radius seat profile to match factory VAG alloy wheels
- Precision machined for a secure, even clamping load
- Sold individually, so you only buy what you need
Important fitment note
This nut is designed for OEM wheels with a radius (ball) seat. Many aftermarket wheels use a conical (tapered) seat instead, and the two profiles are not interchangeable. Fitting the wrong seat type can cause the wheel to work loose and is unsafe. Always confirm the seat type required by your wheels before purchasing.
