Like all StopTech products, StopTech High Performance Brake Fluid is carefully designed to give drivers an edge in the punishing world of high performance motoring. For over a decade StopTech has engineered and delivered race- and championship-winning brake components and systems for high performance street driving as well as pure racing. StopTech High Performance Brake Fluid adds a new dimension to the company’s offerings.Available in STR-600 and STR-660 formulations for high performance street and racing applications respectively, the new StopTech High Performance Brake Fluid is a DOT 4 motor vehicle brake fluid, engineered to optimize brake system performance at high operating temperatures. In addition to guarding against boiling and subsequent loss of efficiency at severe racing temperatures, StopTech Brake Fluid maintains its excellent viscosity, lubricity and non-compressibility.
StopTech Racing Brake Fluid stands out not just for its exceptional performance, but also for its stylish and functional packaging. StopTech Brake Fluid comes bottled in a special metal container that is not only more durable, but also gives the fluid up to 25 percent longer shelf life than typical plastic bottles provide. Both in looks and in performance, StopTech Brake Fluid stands out from the crowd.
StopTech® High Performance Brake Fluid conforms to and exceeds the current specification of U.S. FMVSS 116 (§ 571.116) DOT 4, is road legal, and compatible with modern ABS and other vehicle dynamic control systems. StopTech brake fluid is mixable with all DOT 3 and 4 products.

Check size.
Color: Navy Blue, Size: Large
I normally order a large. This was a little loose. Some may like that. Otherwise, it is a comfortable shirt.

Fantastic super soft Mock Turtleneck short sleeve shirt!
Color: Navy Blue, Size: Medium
COOFANDY Mens Mock Turtleneck Shirts Short Sleeve Casual Basic T-Shirts Ribbed Solid Pullover Top is fashionable and comfortable with a softness I wasn’t expecting. The fabric is excellent quality and just the right thickness for this time of the year. The sizing was perfect as the mock turtleneck short sleeve shirt hugs my body perfectly. I love the way it looks on me and I plan on purchasing a few more. Great addition to my golf apparel!

Don’t Pass On This One! Get Every Color!
Color: Black, Size: X-Large, Color: Black, Size: X-Large
I always brace myself when purchasing clothing off the internet because size recommendations don’t always hold true. I’m glad I flowed my mind and bought an XL instead of the recommended XXL. It fits perfectly. The quality was better than I expected and the neckline was a perfect height and the size was just right (my neck is a 19”). The cost was better than what’s offered in stores. The stretch material adds to the comfort and it’s lightweight; which makes it perfect for those that are hot alot…like me. (I’m 5’10”/ 260lbs / usually a XXL)
