REPLACEMENT ROTOR DISCS ONLY, DOES NOT INCLUDE ALUMINUM HAT.
Competition Motorsport is an Authorized dealer for GiroDisc products and we are one of the largest stocking dealers in the country. Â We ship most products same or next business day to ensure we meet your delivery deadline.
The GiroDisc replacement rotor system is a direct rotor disc replacement for the Giro Disc 2-piece hat and rotor and no modifications are necessary. Â
The rotor and hat mount together through a floating mount system which utilizes 8-10 high strength alloy steel drive pins manufactured by GiroDisc in the USA to our own specifications and are cadmium plated for corrosion resistance. Â The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat. Â The pins are secured by grade 12 cap screws with hardened washers and mounted with anti-noise spring washers to allow for heat expansion while eliminating the rattle and noise associated with floating rotors.
The 2-piece GiroDisc design allows for rotor only replacement to minimize replacement costs and deliver outstanding performance and cooling.

The central hat section of the disc is made from 6061-T6 aircraft specification aluminum. The disc is made from cast iron to the same specification and material as used by professional racing organizations. It is a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.The rotor and hat have a floating mount system, which utilizes 10 high strength alloy steel drive pins, manufactured by Girodisc to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.Once the Girodisc system is in place, simply replace the cast iron rotor when needed. When used with Pagid pads and high-temp racing brake fluid, you have a truly amazing, race-proven solution for your Mercedes Benz.

C3's exacting quality, precise fitment, and a premium hand-polished finish come at a far more reasonable price than the factory Ferrari pieces. Precision-formed in an autoclave from the finest aerospace-grade pre-impregnated dry carbon fiber, each C3 piece matches the 1x1, 3K plain weave of OEM Ferrari carbon perfectly. Fit-and-finish are, of course, impeccable for a truly factory appearance.
FEATURES:
Autoclaved pre-preg dry carbon fiber 1x1, 3K plain weave matched to OEM Ferrari
Clear-coated with automotive urethane, hand polished to a mirror finish
OEM-perfect fit
Each piece installs in minutes without any modifications
KIT INCLUDES:
Four pre-preg dry carbon trim panels
Digitally 3D laser scanned for guaranteed fitment
Autoclave formed in billet aluminum molds at more than 100 psi and 200o F
Experience the Difference of C3 Carbon Products
Competition Carbon Components (C3 Carbon) has been steadily gaining in popularity amongst today’s high-performance driving enthusiasts due to several key factors that help C3 Carbon stand out in a market full of sub-par aftermarket offerings. Each C3 Carbon product is manufactured to provide perfect fit and extreme strength while reducing weight, maximizing quality and ensuring years of exceptional finish. We provide all of this for significantly less money than OEM parts.
Every product we make uses pre-impregnated dry carbon formed in a CNC-machined billet aluminum mold which is manufactured by laser-scanning the OEM component(s) so you know you’ll have a perfect fit, every time. Dry carbon is stronger and lighter than wet carbon, often weighing 1/3 of our competitors’ products. Our manufacturing methods also produce a smoother surface on each part for more dimensional accuracy; shaving edges, widening mounting holes and flexing pieces to make them fit are a thing of the past.
C3 Carbon also applies an automotive urethane clear-coat which is U/V cured for durability and guarantees C3 Carbon parts won't yellow over time.
Many of our competitors use wet carbon (which is heavier), and some use fiberglass with a carbon overlay (much heavier, as the carbon fiber has epoxy literally painted onto it). These materials and manufacturing methods produce a poor finish due to air contamination, and because the epoxy isn’t applied uniformly throughout the weave. These products are also much weaker than C3 Carbon products. Finally, most competitors use a fiberglass mold, which is far less expensive but cannot maintain the strict tolerances we demand of our own products. In the end, the fit and finish simply cannot stand up to C3 Carbon products.

LeMans Prototype-Inspired Endurance Racing Wheel
The Litespeed Racing F1-Ultra v2 Forged Aluminum wheel is inspired by LeMans Prototype (LMP) endurance race wheels, with a deep, flat rim edge that assists with aerodynamics while also making the wheel very stiff. The F1-Ultra V2 features undercut CNC milling on the rim edge to shave weight along with through-hole milling on the spokes for further weight reduction.
The Litespeed Racing F1-Ultra v2 Forged Aluminum wheel is not the absolute lightest wheel we carry, but it is a great choice for those who need a very strong wheel that's engineered specifically for race track use.
Litespeed Racing wheels are competition-proven on tracks across the world, from road courses to autocross to quarter-mile and half-mile top speed races.
Fully Forged From Aerospace Grade 6061-T6 Aluminum
Litespeed Racing uses true fully forged aerospace grade aluminum as the foundation for all of their forged aluminum monoblock and multi-piece wheels. Each forged wheel is precision CNC machined to meet the style, size, offset and load rating of your vehicle.
Forged aluminum is stronger and more durable than standard cast or flow-formed aluminum wheels. The result is a lighter wheel that improves all aspects of performance from acceleration to handling to fuel economy.
Every Litespeed Racing wheel is custom made to fit your specifications for size, offset, color, finish, brake clearance and load rating. Once you've made your purchase, give us a call at (844) 438-7244 to select the specs, color and finish that suit your application!
