Description
Upgrade your BMW or Toyota performance vehicle with the Vargas Turbo Technologies (VTT) M14x1.25 to M14x1.50 Wheel Stud Conversion Kit. Designed to replace factory wheel bolts with a durable stud and lug nut system, this conversion enhances wheel installation, improves serviceability, and provides a stronger, more convenient wheel mounting solution for both street and motorsport applications.
The VTT Wheel Stud Conversion Kit converts vehicles equipped with factory M14x1.25 wheel threads to the more common M14x1.50 thread pitch, making replacement lug nuts easier to source while improving wheel installation and removal. This setup is particularly beneficial for track enthusiasts, frequent wheel changes, aftermarket wheel installations, and spacer-equipped vehicles.
Each stud is forged from cold-rolled 10.9-class steel for exceptional strength and durability. A black oxide corrosion-resistant coating provides added protection against corrosion while maintaining a clean, performance-focused appearance. The studs are engineered with an optimized 85mm overall length, featuring a bull nose tip for easier lug nut engagement and a precision-machined shank for proper wheel alignment and load distribution.
Available in 10-piece and 20-piece configurations, each kit includes matching black open-ended lug nuts, delivering everything required for a complete wheel stud conversion.
