Alloy wheels offer a modern alternative to the original steel Rostyle and wire wheels, providing reduced unsprung weight, improved cooling for the brakes, and a wider choice of tyre fitments. Properly chosen alloys retain the period character of the car while delivering measurable handling and braking benefits. The MGOC Spares alloy wheel range covers three distinct fitment types to suit both standard steel-wheel cars and cars converted to centre-lock wire-wheel hubs, so owners of every Midget specification can find a suitable alloy option.
Minator Sport Alloys
Minator sport alloys are the most popular alloy choice for the Midget, manufactured to the correct offset for direct bolt-on fitment to the standard steel wheel hubs. The wheels are available in two finishes: a polished silver finish that suits cars in lighter colours and brightwork-rich exterior trims, and an anthracite finish that gives a more aggressive contemporary appearance, particularly effective on darker body colours. Both finishes are durable and weather-resistant, requiring only routine cleaning to maintain their appearance.
The standard Minator size is 5x13 inches, with complete wheel-and-tyre packages available fitted with 155/70/13 tyres for a rolling diameter close to the original specification.
Hi-Lite Alloys
Hi-Lite alloys provide a second stud-fit option for steel-wheel Midgets, offering an alternative visual style to the Minator design. Like the Minator, Hi-Lite wheels bolt directly to the original steel wheel hubs using the existing wheel studs, so no modification to the car is required. Choosing between Minator and Hi-Lite is largely a matter of visual preference, both are engineered to the correct offset and provide the same handling benefits over the standard steel wheel.
Centre Lock Alloys
Centre Lock alloys are designed for cars already fitted with wire-wheel splined hub adaptors, using the same knock-on spinner system as wire wheels. This makes them the natural upgrade for wire-wheel cars where the owner prefers an alloy appearance without removing the wire-wheel hub conversion, no changes are needed to the axle, half shafts, or hub adaptors. The spinner retention means the wheel carries no visible bolts, delivering a clean appearance that combines the period wire-wheel mounting system with the modern alloy aesthetic.
Weight and Handling Benefits
Alloy wheels reduce unsprung weight compared to the original steel wheels, which improves the suspension's ability to follow road surface changes and gives a more responsive feel through the steering. Lower unsprung weight also reduces the load on the dampers and bushes, contributing to longer component life as well as improved handling. The larger brake cooling apertures in most alloy designs help dissipate heat during spirited driving, reducing the risk of brake fade on longer descents or sustained braking.
Centre Caps and Fitment
Centre caps are supplied with stud-fit alloy wheels and clip into the wheel centre hub area to cover the wheel nuts. Replacement centre caps are stocked individually for owners renewing damaged or missing items, earlier Minator alloys manufactured before 1999 use a different centre cap specification to later production, so the year of the wheel should be confirmed when ordering a replacement cap. The stud-fit alloys use the existing standard wheel nuts, so no special nuts are required for fitment.
Choosing Your Alloy Specification
The choice between Minator, Hi-Lite, and Centre Lock comes down to the car's existing hub specification and the appearance the owner prefers. Stud-wheel Midgets are suited to Minator or Hi-Lite, chosen by visual preference alone. Cars already converted to wire-wheel hubs, whether from factory wire-wheel specification or a later conversion, are best served by the Centre Lock alloy, which uses the existing hub adaptors without requiring any reversal of the wire-wheel conversion.
