Middlebridge Wheel Centres (Later type)
The wheel centres pictured are fitted to the vast majority of Middlebridge cars. (Very early cars had a small centre cap fitted). These wheel disks are made from a plastic material that clearly goes brittle, loses its chrome look appearance (turns matt grey), the fingers pictured snap off after going brittle and eventually the caps just fall off. New caps are available and occasionally QRG and Graham Walker hold them in stock. Another route and a cheaper one that several owners have successfully taken is to import the units direct from Performance Wheels, Perth, Australia. Below are the contact details for Performance Wheels. Please use the link and navigate to the accessories page and see item 20.
