D2-147 Girodisc Rear Replacement Rotor Rings
$730.00
REPLACEMENT ROTOR DISCS ONLY. INCLUDES NEW MOUNTING HARDWARE. DOES NOT INCLUDE ALUMINUM HAT.
Discovery Parts is an Authorized dealer for Girodisc products and we are one of the largest stocking dealers in the country. 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 Girodisc two-piece hat and rotor and no modifications are necessary.
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 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 two-piece Girodisc design allows for rotor only replacement to minimize replacement costs and deliver outstanding performance and cooling.
Sold/priced per pair.

Racetech RT4100 Racing Seat
2028 Expiry
Announcing the all-new Racetech 4100 Series! The RT4100 is a standard-sized fiberglass race seat. Racetech focused on achieving a lightweight seat shell with optimized geometry, straddling the line between designing the seat to be wide enough in the shoulders to suit the athletic build, but narrow enough to fit in most cockpits. Their patented back-mounted technology has trickled down from the 119 and 129 Series, giving you the option of fixing the seat to the rollcage at shoulder level.
Large harness guides and a removable molded base cushion allow a range of drivers of varying heights to fit. Breathable Spacer fabric, parallel sides and pronounced thigh support round off the features of this accomplished motorsport seat.
OPTIONS
The RT4100WT is 60mm taller and 40mm wider than the standard RT4100.
The RT4100HR and RT4100WTHR include head restraints.
The 4100 Series seats use Racetech RTB1009M alloy side mounting brackets (can be added separately).
