THE STORY BEHIND THE POWER

Owner and founder Gary Conway is a car enthusiast before all things. He has owned and built a number of high performance track and show cars, featured in many automotive magazines and even appearing on television (see our PRESS section).
Gary Conway comes from a family of well respected automotive figures. His father being a well known name in the automotive industry. His business, Air and Sound, went from a small garage in West London fitting car alarms, to building demo vehicles for some of the biggest car audio manufacturers in the world, including Clarion. With this wealth of knowledge behind him it was inevitable Gary would follow suit in the automotive trade. After several years studying Motorsport Engineering and equipped with experience working with a major racing company within the BTCC, Gary founded GCAP Performance.
GCAP's humble beginnings began with installing bolt on performance upgrades from the London workshop. As the company grew, so too did the services offered by the company. GCAP now offer full bespoke tuning packages ranging from basic bolt on parts to custom performance parts made exclusively for the company, in house and by some of the worlds biggest tuning manufacturers.
