Here’s a rundown of Aumotor’s current product range:

1. Forged Titanium Wheel Locks & Bolts

Our flagship product is made from aerospace-grade Ti-6Al-4V titanium alloy, featuring a unique seven-sided head design for enhanced security against wheel theft. With an incredible tensile strength of 1100 MPa, these bolts far surpass the performance of 10.9 grade steel options. The material isn’t just strong and lightweight—it also offers outstanding heat resistance and fatigue durability, making it perfect even for track use.

By reducing unsprung weight, these titanium bolts deliver noticeable improvements in acceleration, braking, and overall handling. Tests show that upgrading to our titanium bolts can reduce rotational mass by up to 40%—equivalent to shedding dozens of kilograms from your car. That means better fuel efficiency and sharper control on the road.

Safety is a top priority. Each bolt undergoes hard anodising for superior corrosion resistance—ideal for coastal or rainy environments. The 7075-T6 washer design ensures a tight fit and prevents loosening over time. Unlike many hollow-head bolts on the market, ours feature a solid head construction for added strength during installation and removal. We also include detailed fitting instructions to help you get the most out of your purchase.

2. Racing-Grade Forged Titanium Wheel Bolts

Designed for maximum weight reduction, these track-focused bolts feature a compact low-profile head. Each bolt weighs just 38 grams! To ensure reliability under extreme conditions, they’ve been tested by TUV and achieved a HV10 hardness rating of 339—a level of quality rarely matched by other suppliers. (Note: HV10 testing is used to evaluate surface hardness and material integrity in precision components)

3. Entry-Level Forged 12.9 Grade Steel Bolts

This versatile option fits most bolt-on wheel applications and includes an integrated washer to prevent loosening caused by vibration. With a tensile strength exceeding OEM 10.9 grade bolts, they’re a reliable upgrade for daily drivers and performance cars alike. We recommend replacing bolts that are over eight years old or show signs of wear beyond 30%. These bolts have passed rigorous TUV and SGS destructive testing, including a wedge loading test tensile strength of 1277 MPa.

By the way, we currently offer fitments for BMW, Porsche, Audi, Mercedes-Benz, Ferrari, and many other popular European and Japanese models (including Nissan GT-R and Toyota SUPRA).

At Aumotor, our strength lies in providing vehicle-specific solutions. Whether you drive a European performance car or a Japanese sports model, we have precisely engineered wheel bolts and nuts to meet your needs. Every product is designed and tested for perfect fitment and performance.
