Rennwerks was born in 2000 and established itself as a winning competitor in Porsche Cup Car and GT Racing in SCCA and IMSA for several years. In 2008, Rennwerks became Rennwerks Performance Inc. and has since celebrated the incredible engineering and artistry of the glorious automobile by providing comprehensive auto repair and upgrade services through our Sprint Motorsports brand! Our deep passion for top-level street performance drives us to provide you with the best OEM Replacement parts, tuning, and performance products in the market through our Rennwerks retail site. With direct access to any desired parts and superior customer service, we can help you turn any of your personalized automotive build dreams into a reality. In 2018, we established DIY or Die Techshop, to provide a professional environment for the 'Do-It-Yourself' car enthusiast to have access to lift rentals and tools to accomplish their car repair and performance desires. Rennwerks Performance Inc also owns the #becausebags brand which helped establish the air suspension "air ride" or "stance" scene by working with Airlift and Accuair to provide unique brackets to make air suspension installations clean and simple.

Our staff has decades of combined experience and training that enable us to provide the best products for all cars- from the old school Datsun and JDM, American Muscle, to new age Porsche, BMW, Mercedes, Audi, and Ferrari vehicles. Our integrity has generated our reputation as the universal automotive expert for classic and luxury sports cars located in heart of San Jose, California. We value direct customer communication and our commitment to absolute customer happiness to ensure your satisfaction.
