A1-104 Girodisc Honda S2000 Front Rotors
$850.00
Honda S2000 Front Rotors
Enhance the stopping power and control of your Honda S2000 with Girodisc 2-piece floating front rotors. Designed as a direct-fit upgrade for the factory discs, these rotors bolt on with no modifications required while maintaining factory brake bias and ABS function. The result is sharper response, reduced fade, and a significant drop in unsprung weight—ideal for both spirited street driving and competitive track sessions.
Each rotor combines a precision-machined 6061-T6 aluminum hat with Girodisc’s proprietary high-carbon cast iron rings. The internal curved vane design acts as a self-cooling air pump, pulling air through the rotor under braking to reduce heat buildup and extend component life.

Goodridge G-Stop High Performance Stainless Brake Lines
This Kit Fits the Honda S2000 AP2 (2006-09)
Goodridge G-Stop high performance brake lines for the Honda AP2 S2000 consist of the finest quality PTFE inner hose covered by a braided stainless steel outer casing. This gives you a much firmer, more responsive brake pedal by eliminating the “spongy” feel that often accompanies stock rubber brake lines, making them ideal for the very high brake pressures seen during HPDE track days. G-Stop High Performance Brake lines are abrasion and corrosion resistant so they last a long time under harsh conditions.
Goodridge G-Stop high performance brake lines are direct bolt-on replacements for all of the rubber brake lines in your S2000's brake system1. Four brake lines are included in each kit, with hose ends and brake line brackets that match the car’s original equipment.
Conforming to Federal Motor Vehicle Safety Standard Number 106, Goodridge G-Stop high performance brake lines are U.S. DOT certified and T.U.V. approved. All Goodridge G-Stop brake lines go through a nine-point Quality Assurance testing process that includes measuring tensile strength and the ability to sustain line pressures to 3,000 psi.

AP Racing Radi-CAL R4 Racing Brake Fluid (500 ml)

AP Racing Radi-CAL R4 Racing Brake Fluid
Among the Highest Dry Boilings Point On The Market Today
AP Racing Radi-CAL R4 racing brake fluid has an ultra-high typical dry boiling point, at 644º F / 340º C. Radi-CAL R4 racing brake fluid has been designed to perform better than any other product at the extremes of heavy-duty braking in top levels of professional racing.
AP Racing Radi-CAL R4 has outstanding resistance to vapor lock and pedal fade under the most exacting conditions. A higher vapor lock point means a firmer brake pedal at the extremes of brake temperatures. Enhanced lubricity means R4 is a better lubricant than other market-leading racing brake fluids. This helps extend the life of the metal moving parts in your brake system while increasing system efficiency.
Radi-CAL R4 can be mixed with other DOT 3 and DOT 4 racing brake fluid, although for maximum performance your braking system should be thoroughly purged with R4 fluid.

AP Racing Radi-CAL R3 Racing Brake Fluid
Designed for the Top Levels of Motorsports
AP Radi-CAL R3 Racing Brake Fluid was developed for use in very-high-temperature racing conditions. It conforms to or exceeds FMVSS 116, DOT 4, SAE J1703 and J1704 standards. AP Racing Radi-CAL R3 Racing Brake Fluid is one of the most popular brake fluids at the highest levels of professional auto and motorcycle racing. It was specifically developed for coping with extraordinary temperatures, such as those encountered when running a carbon/carbon composite brake system.
To ensure that the fluid stays fresh, AP brake fluids are furnished in 500 ml (16.9 oz) easy-pour plastic bottles with double-sealed caps. When switching your fluid to AP Racing Radi-CAL R3, we recommend purging all of the old fluid from the system. Three to four bottles of fluid are enough to completely replace existing brake fluid and still have enough left over for a bleed at the track to remove any remaining air bubbles.

CMS Performance
CMS Performance RF1 Racing Brake Fluid (500 ml)
from $24.95
CMS Performance RF1 DOT4 Racing Brake Fluid
Real Life 622º Boiling Point Without the Real High Price
RF1 Racing Brake Fluid from CMS Performance is a fully-synthetic DOT4 brake fluid formulated to provide extraordinary performance under the most demanding high-temperature racing and track-day conditions. With a dry boiling point of 622º F / 328º C, RF1 exceeds all DOT 3 & DOT 4 requirements and is compatible with all DOT 3, DOT 4, and DOT 5.1 fluids.
Note: RF1, like all DOT 4 brake fluids, is not compatible with DOT 5 silicone-based or any mineral-based brake fluids.
On the race track, there is perhaps no single safety system more important than your brakes. No single part of that system is more critical than brake fluid, given the extraordinarily high temperatures it operates under. At CMS Performance, we got tired of (and a little nervous) using "racing" brake fluid at the race track that didn't live up to its claimed performance when things got hot. We found more than a few brands whose product was all hype and not high performance.
No Hype. All Performance. No Kidding.
So we did something about it. CMS Performance RF1 is manufactured in partnership with Orthene, maker of the also-excellent Halo P1 racing brake fluid and a brake fluid supplier to many racing teams in Formula 1, WEC, and other professional series. RF1 was formulated to maintain consistent viscosity, lubricity, and compressibility at the extreme system temperatures and line pressures found in racing and track days.
The bottom line is this: you can spend a lot more on brake fluid, but it's hard to find higher-performance than RF1 Racing Brake Fluid.
CMS Performance RF1 Racing Brake Fluid Details:
Manufacturer: CMS Performance
Manufacturer part no.: CMSRF1
Typical dry boiling point: 622º F / 328º C
Typical wet boiling point: 399º F / 204º C

A Word About Flushing Brake Fluid
All brake fluid degrades over time (not mileage), attracting water as it ages, which, at high brake temperatures, can lead to fluid boil and brake fade or failure. That's why the "wet" (aged) boiling point of any brake fluid is substantially lower than the "dry" (new) boiling point.
To maintain maximum braking performance, Competition Motorsport strongly suggests replacing your brake fluid before every track event, but at least every three months if you're consistently racing and/or driving at track days. It's cheap insurance against learning about brake fade the hard way!

AP Racing Radi-CAL R2 Racing Brake Fluid
Outstanding Performance in High-Heat Braking Applications
AP Radi-CAL R2 racing brake fluid was developed for the extreme abuse of heavy race cars competing in endurance events. AP Racing Radi-CAL R2 fluid has a dry boiling point of 593º F (312º C), and was developed for racing applications where high brake temperatures are common (e.g., when using carbon discs) and very high temperature brake fluid performance is required.
Before using AP Racing Radi-CAL R2 fluid, any existing brake fluid should be drained completely from the car's brake system. The system should be thoroughly purged with new R2 and can then be filled completely with fresh R2 fluid.
