1963 Mini Cooper: Modified Through Generations

1963 Mini Cooper: Modified Through Generations

While purists may raise an eyebrow at the Zeemax body kit and 13 inch alloys, it’s impossible to deny the car’s presence...

Among a sea of cars at the 2024 Millport Classic Car Show, David Seditas’ 1963 Mini Cooper stood out more than the rest  catching the attention of every passerby. I took the opportunity to arrange a meeting with David to photograph the car and learn more about its history.

In 1988, the British Racing Green Mini was taken as a part exchange against some mechanical work completed by David’s father; It was used by the family until circa 1996 when it became tired and was tucked away in David’s fathers shed.
A couple of years later, David’s uncle took ownership and embarked on a rescue mission to restore the car to its former glory with a twist. This restoration would take 2 years from start to finish using a host of new parts and reconditioned original parts. The photo below shows its condition prior to the restoration.

The original shell, sadly beyond saving, was replaced with a new Rover shell, complete with a Zeemax bodykit. Now, while this choice might upset a few folk, it’s important to remember that back then, you could pick up a used Mini for around £150 and no one could have imagined they would reach todays prices!

A set of 13x7” Superlite alloy wheels were fitted to fill the flared arches.

Moving onto the interior… The original rear bench remains intact, but the front seats were replaced with seats from a Metro Turbo for a more modern look – retrimmed in a very 90’s, OEM Rover fabric. 

The dashboard is particularly eye-catching. A fully custom piece, filled with a collection of Smiths gauges, each one seemingly plucked from different periods. A Tomei AFR meter keeps tabs on the engine’s air-fuel ratio, while a mixture of switches and dials creates a unique, almost patchwork effect, blending modern functionality with vintage aesthetics. It’s this mixture of old and new that really sets David’s Mini apart from the more conventionally restored examples. The touches, like the Sabelt driver’s harness and Britax passenger harness, are reminders that this Mini has always been as much about the driving experience as it is about looks.

The Sony MiniDisc radio mounted in a custom roof box, along with a 6-disc MiniDisc changer in the boot, adds a perfect nostalgic nod to the 1990s!

Under the bonnet, the original 1275cc engine has been thoroughly upgraded. A Piper cam of unknown profile keeps things lively, while the 7-port alloy head and twin Weber 40 DCOE carburettors ensure the Mini has the bite to back up its bark. The LCB exhaust with its DTM backbox completes the car’s distinct, throaty soundtrack.

Yet, despite these significant engine upgrades, it's the precision of the driving experience that stands out. A close-ratio gearbox and quickshift give the Mini a wonderfully tight, engaging feel, while an ultralight flywheel and fast-road AP clutch ensure it’s quick to respond to even the lightest throttle input. It’s clear that this Mini wasn’t just built to look good—it was designed to be driven hard and enjoyed.

The handling is also a step up from the Mini’s original spec. David’s uncle opted for a Metro Turbo vented brake setup on the front and Minifin drums on the rear, a considerable improvement in braking power for such a small, lightweight car. Meanwhile, SPAX adjustable suspension, combined with a Hi-Lo kit, ensures that the car feels as agile as it looks. It rides lower than a stock Mini, hugging the road through corners with that signature go-kart-like precision that Minis are famous for.

During the Winter of 2022, David decided it was time to give the car a refresh. The car was completely stripped and repainted in the original British Racing Green. However, this time a few subtle changes were made. David opted for an Old English White roof and added a black surround to the rear window which blends perfectly with the Perana removable window louvre. In addition to the cosmetic changes, a quick release bonnet was fitted with a cleverly integrated intake slot to improve engine cooling.

When talking to David about his beloved Mini, it’s clear that this car means much more than just a weekend toy. For him, it represents a family legacy. Passed from his father, to his uncle, and now back to him.
