Give your A90 Supra the upgrade it deserves with the Thunder Bolts Club Sports Titanium Forged Stud Conversion Kit—crafted for serious performance and street appeal. Unlike factory wheel bolts, stud conversions make mounting wheels faster, safer, and more precise—especially when dealing with larger or aftermarket wheels. Whether you’re chasing lap times or fine-tuning your stance, this kit delivers the strength and convenience needed for repeat wheel swaps and aggressive fitments.
Forged from aerospace-grade titanium (ASTM B348 Ti-6Al-4V Gr.5), these 75mm or 90mm stud bolts are ultra-lightweight and race-proven, offering corrosion resistance and durability at a fraction of the weight of steel. Designed with security-special heads and a conical seat for proper load distribution, the kit also includes all the tools and thread locker you need for a straightforward install. Compatible with spacers up to 15–30mm, this is the ultimate stud conversion for those who demand both function and form.
