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.

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!

Antigravity
Antigravity Clampless Starting Harness | XP-20 / XP-20-HD Jump-Start Cable
from $29.00
Antigravity Clampless Starting Harness (XP-20 / XP-20-HD)
Quick, Hassle-Free Jump Starts Without Clamps
The Antigravity Clampless Starting Harness is the ultimate time-saver for anyone using an XP-20 or XP-20-HD Micro-Start. This clever accessory connects directly to your battery, letting you jump-start or energize your vehicle without using jumper clamps — and without removing your motorcycle seat, opening your hood, or even touching the battery. It’s the fast, clean way to power up your ride when the battery goes flat.
Available in two lengths, the 20-inch version is ideal for motorcycles, while the 45-inch version is perfect for cars and trucks. Simply connect the ring terminals to your battery and route the harness to an accessible spot. When needed, plug your Micro-Start directly into the harness and jump your vehicle — no tools, no panels, no wasted time.
Key Features
Clampless Convenience: Jump-start or energize your vehicle without clamps or accessing the battery.
Time-Saving Design: No removing seats, opening hoods, or digging for your battery.
Two Lengths Available: 20-inch for motorcycles; 45-inch for cars and trucks.
Direct Connection: Ring terminals connect to battery; opposite end plugs into Micro-Start jump-start port.
Easy Access Routing: Harness can be tucked away for fast connection in emergencies.
Protective Dust Cap: Keeps connector clean when not in use.
How It Works
Connect the ring terminals directly to your vehicle’s battery.
Route the harness to an accessible location (outside hood, trunk, or seat).
When needed, plug your XP-20 or XP-20-HD Micro-Start directly into the harness to energize or jump-start the vehicle.
Tip: On modern vehicles that lock down when the battery dies, route the 45-inch harness outside the trunk or hood so you can energize the vehicle to unlock it.
Safety Notes
Remove the Micro-Start from the harness as soon as the vehicle starts or is energized.
Do not leave the Micro-Start connected for more than 3 minutes when energizing.
Do not leave the Micro-Start connected more than 90 seconds after a jump start to prevent back-charging damage.

Motul RBF 600 Racing Brake Fluid (500 ml)
from $29.00
Motul RBF 600 Racing Brake Fluid
Motul RBF 600 is a 100% synthetic high-temperature DOT 4 brake fluid for hydraulic-actuated brake and clutch systems. RBF 600 is specifically designed to resist the high temperatures of steel or carbon-composite racing brakes and clutch systems.
Motul RBF 600 far exceeds the standards of ordinary DOT 3 and DOT 4 brake fluid. The RBF 600 container is filled with nitrogen to increase shelf life and eliminate contamination while factory sealed. Its extremely high dry- and wet-boiling points help prevent vapor lock and brake fade during hard use.
Extreme Thermal Resistance and Stability
The elevated dry boiling point of RBF 600 (593° F / 312° C) enables effective braking even under extreme conditions like racing competition, mountain driving, etc.
Very Effective in Rainy Conditions
The high wet boiling point (420°F / 216° C) of Motul RBF 600 is superior to conventional brake fluids, providing particularly efficient braking in rain while reducing the risk of vapor lock.
Note: do not mix DOT 4 brake fluid like Motul RBF 600 with DOT 5 silicone-based or conventional mineral-based brake fluids.
