About Us


Being a car enthusiast has been a life long hobby. From Japanese, American, and now European, we have been a part of many growing, and already established, motorsport communities. So often we have seen performance parts and car tuning available for platforms that seem to be just out of economic reach for the average enthusiast. We look to change that with our affordable products.


With over 30 year of combined automotive experience, we know what our customers look for in products. We apply our knowledge to make durable products and use our experience to ensure we provide the best price without sacrificing quality.
