Sparco EVO QRT Racing Seats As Sparco's most well known competition seat, it was a no-brainer to provide the refreshed Evo with Sparco's QRT Ultra-Light Technology. Not content to leave well enough alone, Sparco went a step further by improving the overall fit and feel of the  Sparco Evo QRT. Starting with the shoulder bolsters, Sparco trimmed down the width to help them fit into smaller cars without sacrificing support. Sparco then lowered the side bolsters just enough to improve ingress/egress into/out of the car. Finally, the shoulder belt guides have been raised for improved harness fit in all drivers. With small sports cars in mind (the Sparco Evo QRT fits perfectly in a Miata!), the Sparco Evo QRT is sure be a mainstay at the track!

A2-050 Girodisc 2pc Rear Brake Rotors (Discontinued Design) Fits Lamborghini Huracan / Lamborghini Gallardo 2009-2012 / Audi R8 Discontinued New old stock rotor.  These have the straight grooves as images show, not the new curved grooves.  Final Sale, no returns or exchanges. The GiroDisc system is an upgrade to a 395mm 2-piece steel rotor and aluminum hat combination and is a direct replacement for the OEM brake disc.  The 2-piece floating disc will bolt directly to the car and work with OEM calipers perfectly.  By upgrading your brakes with these lightweight high-performance replacements as opposed to a big brake kit, your factory bias is maintained as well as your ABS efficiency.  The Giro Disc rotors are lighter than OEM pieces.  The reduction in rotational and unsprung weight allows for quicker acceleration and suspension response. When used with Pagid or PFC performance brake pads, and Competition Motorsport RF-1 brake fluid (also available from CompetitionMotorsport.com), you have an amazing solution to overheating, cracking and warping rotors. The central hat section of the disc is made from 6061-T6 aircraft specification aluminum.  The disc is manufactured from cast iron which is constructed in the USA and is made to the same specification with the same material used by professional racing organizations.  The rotors curved vane design was developed in racing and acts as a centrifugal pump to force cooling air through the disc.   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.  The alloy drive pins transfer the load from the brake action while maintaining the axial and radial float between the disc rotor and hat.  The pins are secured by grade12 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 as well to minimize future replacement costs and deliver outstanding performance and cooling. Sold/Priced per pair.

Ferodo FRP3031 Brake Pads Ferodo DS3.12 Brake Compound Details The DS3.12 is the latest evolution in Ferodo's incredible DS line. Sports cars today have more of everything: more horsepower, more sophisticated aero, higher curb weights, and stickier tires. These attributes place serious demands on a vehicle's brake system. The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands. The Ferodo DS3.12 is a top-tier endurance racing brake pad compound built for maximum fade resistance, high friction, and extremely consistent performance at elevated temperatures. If you need a Ferodo track brake pad for aggressive braking, long sessions, and serious motorsport use, DS3.12 is one of the strongest options in the lineup. The DS3.12 compound provides strong initial bite, a highly stable torque curve, and dependable braking performance in demanding track conditions. It is ideal for experienced drivers, endurance racing, and high-grip applications where repeatable stopping power matters most. Maximum fade resistance in the Ferodo range High friction and strong initial bite Very consistent braking response at track temperatures Excellent durability in endurance racing use Best for: advanced track-day drivers and racers who want a high-performance race brake pad with elite heat capacity and confidence-inspiring consistency. Note: DS3.12 is a full race compound and may produce increased dust, disc wear, and reduced cold performance compared with street-oriented pads. Ferodo DS1.11 Brake Compound Details The DS1.11 has a lower mu than the DS3.12 at all temperatures and can be characterized as a moderate mu pad vs. other endurance racing compounds. They require more pedal force than the DS3.12, and they have a slightly declining torque curve as temperatures rise. As they get hotter and you dive deeper into a turn, you may feel like you need to push a little harder on the brake pedal to elicit the same response (which is a feel many drivers actually prefer). Some drivers feel that the DS1.11 is more controllable on street tires than DS3.12 since ABS cannot be activated as easily. It will last a fairly long time vs. many other pad compounds on the market but does not last quite as long as the DS3.12. They are very gentle on discs at track temperatures when a proper pad transfer layer is maintained. The DS1.11 also has an outstanding max temp and fade resistance, just not quite as high as 3.12. We're not aware of anyone who has faded them, and most people differentiate between the DS1.11 and DS3.12 based on feel. The Ferodo DS1.11 is a proven endurance racing brake pad compound designed for drivers who need outstanding fade resistance, long pad life, and precise control under repeated high-temperature braking. For track cars and serious HPDE builds, DS1.11 is a trusted Ferodo race brake pad with a strong reputation for consistency. This DS1.11 features stable braking performance, excellent modulation, and durability in demanding track conditions. Compared with more street-focused compounds, DS1.11 is better suited to aggressive lapping, endurance sessions, and drivers who value a progressive pedal feel. Exceptional fade resistance for track use Long wear characteristics in endurance-style driving Progressive, controllable pedal feel Excellent choice for HPDE and racing applications Best for: drivers looking for a track brake pad with durability, modulation, and high-temperature stability for repeated hard use. Note: DS1.11 is a race compound and is not ideal for customers seeking low noise, low dust, or refined street manners. Ferodo FRP3031 Comparison Chart Out of all the pad compounds we've ever tested, from all manufacturers, the Ferodo DS3.12 shows the flattest torque curve across the broadest temperature range. That means on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same, providing tremendous consistency and repeatability. The DS3.12 has a higher mu (µ) than Ferodo's other compounds, so not as much pedal pressure is required to initiate the desired response. It is also un-fadable, showing no drop in performance at any temperature your brakes will ever see. Ferodo FRP3031 Coefficient of Friction (Mu) Comparison Chart In dyno testing, the Ferodo DS3.12 has shown superior wear rates to the other Ferodo compounds, while remaining kind to brake rotors. We believe the Ferodo DS3.12 will become the gold standard by which other race compounds will be judged. Ferodo FRP3031 Operating Temperature Comparison Chart **Designed for use with iron brake rotors only. Not for use with carbon-ceramic rotors.**
