I race in a car with a Nick Cole built cage. The service was incredible. Fully tailored. My cage wasn't a generic 'bolt-in, off the shelf' but a full custom built cage, built around me personally for what is now my multiple race winning Porsche.
Cole's AutoTech built the custom exhaust on my BMW M140. I was impressed from start to finish. The sound is awesome, a guaranteed smile on startup every morning.
