What We Do
Kent Auto Developments (KAD) was founded in 1990 with a single, ambitious goal: to reimagine the A-Series engine with a performance-driven 16-valve twin-cam conversion. Designed, and machined entirely in-house, the original KAD 16v head transformed the way people thought about classic Mini performance — bringing modern engineering into a historic platform.
Proven on track and refined through years of motorsport feedback, that breakthrough product laid the foundation for everything we stand for: precision engineering, in-house production, and a refusal to compromise on quality.
We believe in building things properly, from the first prototype to the final product. And that same mindset continues to drive our work today.
More Than Engines
While our engine components remain highly regarded, suspension and braking systems now make up a significant part of our business — and for good reason.
We’ve applied the same rigorous engineering approach to every corner of the car. From lightweight billet 4-pot calipers to adjustable front and rear suspension kits, anti-roll bar systems, hubs, and bespoke geometry solutions, our chassis products are designed to give drivers serious confidence — whether they’re on the road, track, or pushing for a podium finish.
Everything is built in-house, tested on track, and constantly refined to give you sharper handling, predictable feedback, and lasting performance. These aren’t repackaged kits from other manufacturers — they’re KAD-developed solutions, designed from the ground up for serious enthusiasts and racers alike.
In-House Manufacturing. Total Control.
At KAD, we believe that control over the process leads to control on the road. That’s why nearly every component we offer is made right here in our Kent facility. Our fully equipped workshop includes:
• 3 & 5-axis CNC machining
• CNC turning
• Gear cutting
• Engine dyno testing (up to 800 bhp)
• Flow bench testing
• Block boring, honing & line boring
• Cylinder head work & modification
• Dynamic crankshaft balancing
• Vapour blasting
• Powder coating
• Shot peening
• Super finishing
• Ultrasonic cleaning
With in-house CAD/CAM and hands-on expertise at every stage, we’re able to develop, test, and perfect our parts without outsourcing — giving you peace of mind with every product.
Built for Minis. Engineered for More.
Though the Classic Mini remains the heart of our operation, our work spans far beyond it. We've earned a growing reputation for high-quality work on a range of platforms — from custom performance builds to historic motorsport restorations, including the iconic Aston Martin DB-series straight-six engines.
Whether you need a dyno-tested engine package, a road-ready brake upgrade, or a full competition-grade suspension setup, KAD delivers components you can rely on — KAD delivers components you can rely on — engineered in-house, tested on track, and trusted for over 30 years.
