Even if you're not running StopTech performance brakes out on all four corners, you can still pour some of that race-winning magic right into your master cylinder. StopTech High Performance Racing Brake Fluid is an ultra-performance DOT 4 brake fluid that's engineered to optimize high-temperature brake performance.

Better known as ‘brakes in a bottle', StopTech performance brake fluid gives racers and enthusiasts the braking edge they need. Higher boiling points deliver pedal consistency under extreme driving conditions. And, even at severe racing temperatures, StopTech brake fluid guards against boiling and loss of efficiency while maintaining superb viscosity, lubricity and non-compressibility.

For high-performance street driving, go for the StopTech STR-600 formula. And for radical track action, pour in the race-ready StopTech STR-660. Both come in a durable metal bottle for longer shelf life over plastic. Both are street legal and can be mixed with other DOT 3 and 4 fluids. And, both work with ABS and dynamic control systems. And stop the presses—StopTech backs your High Performance Racing Brake Fluid with a 30-day warranty.

I changed my brake fluid to the STR660 prior to a track day at Road America. Drove 3 half hour sessions and had zero brake problems. The brake pedal maintained its height and firmness throughout the day. Would definitely use this fluid again.

This fluid got the job done. It holds up well for daily use as it should. I have yet to fully test how it will perform during heavy street use but sure it will reach expectations if not exceed. Good for the price!
