Brey Krause R-1120 Harness Bar C6 Corvette
$1,017.38
Brey Krause R-1120 Harness Bar C6 Corvette
The Brey Krause Model R-1120 Harness Bar for the C6 Corvette properly locates and supports racing shoulder harnesses relative to the driver. In the case of an accident, it helps protect the driver's shoulders and spine. The harness guides also prevent excessive shifting and fatigue of the driver during the high G loads of cornering and braking. Our bars are easy to install and remove, and will get you ready for the track in just a few hours!
NOTE: Because of mounting locations in the C6, the B-pillar plastic sail panel covers will require two holes to be drilled through them. Brey-Krause provides plastic plugs to cover the holes if the bar is ever removed. Sail panels replacements can be ordered from your GM Dealer (Part 15277640 for driver side, and 15277641 for passenger side) if the plastic plugs are not the desired solution. Strength requirements for harness mounts are considerably greater than those for harness guide bars since they must support the entire load applied to the belts.
Brey Krause R-1120 C6 Harness Bar Details:
Manufacturer: Brey Krause
Manufacturer Part Number: R-1120
Material: Type 304, stainless steel
Finish: Powder coated in durable black wrinkle-finish
Weight: 17.2 lbs.
Installation: Bar attaches to factory mounting points in "B" pillars.

Why Upgrade to Girodisc?
Whether you're chasing lap times or just want better pedal feel on canyon runs, Girodisc rotors are built to perform under the heat and stress of motorsport. The floating rotor design combats cracking and warping. With better airflow and reduced weight, your suspension responds quicker, your brakes stay cooler, and you stay in control longer.
FAQs: Girodisc A1-032 2pc Front Brake Rotors
Do I need to modify anything to install them? No modifications are required. These rotors bolt directly to your car and work with your factory calipers and brake system.
Can I reuse the aluminum rotor hats in the future? Absolutely. Girodisc designs their systems so you can replace just the iron rings when they wear out, keeping costs down over time.
Are these rotors noisy like other floating designs? No. Girodisc includes anti-noise spring washers to eliminate rattling typically associated with floating rotors, making them quiet and track-ready.
Pair these rotors with Pagid or PFC pads and RF-1 racing brake fluid from Competition Motorsport for a complete braking solution that won’t quit — even when the track temp soars.

Final sale, no returns or exchanges
These are discontinued new old stock rotors. They have the straight slots as images show, not the new curved slots. They are brand new in the original Girodisc boxes.
Upgrade Your BMW F8x To The Best Racing Rotors Available
If you have a BMW M2, M3, or M4 with blue calipers and iron rotors, this Girodisc floating iron rotor system is a direct replacement for your BMW front rotors. No modifications to your car are necessary. The 380mm diameter rotors will bolt directly to your BMW and work with the original blue calipers perfectly. By upgrading your BMW brakes with lightweight high-performance replacements, your factory bias is maintained as well as your ABS efficiency.
Girodisc two-piece floating rotors are lighter than OEM brake rotors. This reduction in rotational mass and unsprung weight allows for quicker acceleration, sharper steering, and faster suspension response.
When used with Pagid or PFC performance brake pads and CMS RF-1 brake fluid (available from Competition Motorsport), you have an amazing solution to overheating, cracking and warping rotors.
The central hat section of each Girodisc is made from 6061-T6 aircraft specification aluminum. The disc is manufactured from cast iron constructed in the USA, 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 ten high strength alloy steel drive pins manufactured by Girodisc in the USA to their 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 disc-only replacement as well, minimizing future replacement costs and delivering outstanding performance.

This Girodisc system is a direct replacement for OEM Porsche steel (cast iron) rotors1 with the use of the provided caliper spacers. The Girodisc rotors are slightly larger than the stock Porsche rotors at 350mm vs. 340mm, providing greater braking force and cooling capacity. The Girodisc front rotors are approximately 21.0 lbs. vs. 24.4 lbs. for the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.

Competition Motorsport is an authorized dealer for Girodisc products. As one of the largest stocking dealers in the country, we ship most products the same or next business day to ensure we meet your delivery deadline.
This Girodisc system upgrades your Porsche's OEM brakes to a two-piece steel disc and aluminum hat. This two-piece "floating rotor" design will bolt directly to your GT2 or GT3 front and work flawlessly with the OEM calipers. Upgrading your brakes to lightweight, high-performance Girodisc rotors, you maintain the factory brake bias and ABS effectiveness.
Each rotor is 5.6 pounds lighter than an OEM rotor, reducing rotational and unsprung mass giving you stronger braking and faster suspension response. Combined with Pagid or PFC performance brake pads and Competition Motorsport RF-1 brake fluid, Girodisc rotors are the ultimate solution to overheated, cracked, warped rotors that result from high-performance driving.
The central hat of the rotor is made from 6061-T6 aircraft aluminum. The disc is manufactured in the USA from the same cast iron used by professional racing organizations. Its curved-vane design, developed in racing, acts like a centrifugal pump forcing cool air through the disc.
The disc and hat mount together through a floating mount system using ten cadmium plated, high-strength alloy steel drive pins manufactured by Girodisc.

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.
