VTT BMW/Toyota M14x1.25 to M14x1.50 Wheel Stud conversion Kits

VTT BMW/Toyota M14x1.25-to-M14x1.5 Wheel Stud Conversion Kit

Convert supported BMW and Toyota M14x1.25 wheel-bolt hubs to a conventional M14x1.5 stud-and-lug-nut arrangement. The conversion simplifies wheel changes and makes replacement M14x1.5 lug hardware easier to source.

Stud Specifications

• Cold-rolled class 10.9 steel construction
• Black-oxide finish
• 85 mm overall length
• 75 mm total thread length
• 10 mm bull nose for easier lug-nut engagement
• 12 mm hub-side threaded section
• 12 mm unthreaded shank
• 48 mm wheel-side threaded section

Kit Contents

• Ten or twenty M14x1.25-to-M14x1.5 black conversion studs, as selected
• Ten or twenty M14x1.5, 19 mm-hex black open-ended lug nuts, as selected

Fitment

For supported Toyota A90/A91 Supra and applicable BMW F8X and G-Series configurations using M14x1.25 hub threads. Confirm hub thread, wheel-hole diameter, lug-seat style, spacer thickness, and required thread engagement before ordering.
