About Us

Kent Auto Developments began manufacturing in 1990 with a 16 valve twin cam cylinder head conversion to breathe new life into the venerable A series engine.

The KAD head was cast in aluminium alloy and furnished with high quality, performance components. We proved and improved our prototype at the race track, testing and developing race by race where preparation was key. The philosophy was a simple one: highest quality, sensibly priced.

Over the last 30 years we have continued to design and innovate, building a vast catalogue of inspiring parts and components spanning engine, suspension & braking.

Whether you want a ready to race dyno tested engine and gearbox unit, or are looking to build the ultimate performance road/race Mini or derivative yourself, we're the place to start!
