I’m Curt Brown, and at Curt Brown Racing, I have over 25 years of experience in building fast turbocharged street, drag, and road-race cars. With the combination of my knowledge and experience, quality US or Japanese parts, and lower business overhead than competitors, I can give you the best “bang for the buck” in competition machine work and performance parts sales and service.​
