## History

Compomotive built its Midlands name in the era when British rallying was a national industry: motorsport wheels for the forest-stage economy — the MO's multi-spoke design becoming the visual default under Mk2 Escorts, Group A machinery and the clubman fleet, with the TH turbofan and other ranges serving circuit and road-tuning fashion. The construction philosophy matched the customer: strong castings priced for a discipline that bends wheels as consumables, in the fitments (13- and 15-inch strongholds) British rallying actually runs.

The marque's persistence is the story's second act: where many period wheel names died with their factories, Compomotive continues manufacturing — meaning historic rally builds can buy new MOs in period style, a supply reality that anchors the whole market for the design.

Used MOs circulate through the Escort economy in volume: sets and singles at forest-sale prices, condition tiers from fresh-painted to stage-scarred, and the diligence the standard rally-wheel law — straightness, cracks, repair honesty — with new availability capping used pricing at refreshingly sane levels.

## Palmarès

Under British and Irish rally championship machinery from the Group 4 Escort era through Group A to today's historic scene — the forest record of clubman rallying's default wheel, accumulated over four decades of stages.

## What to check before you buy

New availability sets the ceiling: Compomotive still makes MOs, so used sets price against fresh ones — pay only for verified straightness (spin-check), crack-free castings (inspect spoke roots and rim edges after forest lives) and honest repair disclosure. Fitment verification for your build (PCD, offset, the 13/15-inch stronghold sizes) is routine but essential. Period-original wheels for concours-minded historics carry modest patina premiums; for actual stage use, condition beats age story every time. Singles supply for crash replacement is healthy — the practical ownership advantage of a living manufacturer.

## Did you know

- The MO under a Mk2 Escort is British rallying's default photograph — wheel and car so paired that historics specify the combination as period correctness.
- Compomotive's survival makes it rally heritage you can order new — the rare period brand where authenticity and fresh manufacture coexist.
- The TH turbofan's road-fashion fame subsidised the motorsport ranges for years — disco aesthetics funding forest hardware.
