How to Measure Your Head for a Properly-Fitting Racing Helmet
The most effective auto racing helmet is one that fits your head properly. Your helmet should fit snug all around your head without putting undue pressure on any point. It should not move around when you shake your head side-to-side or up-and-down. (If it does, imagine what it will do in a crash.)
To measure your head, have an assistant use a dressmaker's tape or a piece of string to measure the circumference of your head. Start at a point about an inch above your eyebrows, looping around the back of your head at the point that results in the largest measurement, and finally around to the front again. It's a good idea to take two or three measurements to make sure you have the largest one.
This helmet will ship with signature required for delivery.

Audi TT RS (8J) — All model years equipped with OEM front brakes
Features
The central hat section is crafted from U.S.-sourced 6061-T6 aircraft-grade aluminum for strength and lightness. The rotor rings are made from Girodisc’s proprietary cast iron, poured and precision-machined entirely in-house in the USA. Each disc uses a curved vane design developed through motorsport testing to act as a centrifugal pump, drawing cooling air through the rotor to lower temperatures and reduce fade.
The floating mount system connects the rotor ring to the aluminum hat using 8 or 10 high-strength alloy steel drive pins, cadmium plated for corrosion resistance. These pins are secured with grade 12 cap screws and hardened washers for maximum durability. Anti-noise spring washers allow for thermal expansion while eliminating rattle, ensuring smooth, quiet operation both on the street and track. The floating design also allows the rotor to self-center between pads, maintaining consistent brake feel under all conditions.
Once installed, the Girodisc system makes future maintenance simple — only the cast iron rotor rings need replacement when worn, while the aluminum hats can be reused for years of service.
FAQs: Audi TT RS (8J) Front Rotors
Do these rotors fit my Audi TT RS without modifications? Yes, the Girodisc system is a direct bolt-on replacement for OEM rotors and works perfectly with factory calipers.
How much lighter are these than stock? Each Girodisc rotor is approximately 7 lbs lighter per corner than the OEM rotors, improving acceleration and suspension performance.
Are these suitable for track use? Absolutely. The Girodisc rotors are engineered to withstand high temperatures and repeated heavy braking while maintaining excellent pedal feel and durability.
What makes the Girodisc rotors different from other aftermarket options? Girodisc rotors are fully machined in the USA from proprietary cast iron and use aircraft-grade aluminum hats for optimal strength-to-weight ratio and long-term reliability.
Do I need to change my brake pads? You can continue using your factory pad shape or upgrade to high-performance compounds — Girodisc rotors are compatible with all OEM-spec pads.
