Grayston Motorsport Accessories

Why Grayston

Grayston Engineering has been manufacturing motorsport accessories from its base in Chessington, Surrey since 1978, and this range is what happens when a business spends nearly five decades making practical racing hardware. The Grayston rally parts catalogue covers bonnet pin plates, boot springs, wheel studs, map pockets, pull cables, and everything else a serious race or rally car needs to be built properly. Here's what to look for:

• UK manufactured by Grayston Engineering Limited, an established name in UK motorsport hardware since 1978

• Practical over cosmetic: parts that solve real problems, from bonnet pins and wheel spacers to mud flaps and boot springs

• Serviceable and durable: high strength materials and components chosen for demanding events, prioritising serviceability

• FIA compliant options: the range includes FIA-branded parts such as the Grayston FIA Battery Master Cut Off Switch, widely used across UK and Irish club motorsport 

Choosing the Right Grayston Product

The Grayston catalogue is wide. Here's how the range breaks down by use case:

Grayston Bonnet Pins & Boot Springs Explained

Bonnet pins are what Grayston is best known for, and the range covers most competition scrutineering requirements. Choose the right type for your bodywork, regulations and access needs.

• Competition Bonnet Pins (GE52 series): The classic quick release slide action pins, as used by many major works rally teams. Slide plate and pin made from high tensile aluminium or stainless steel. Best for traditional rally car preparation and quick access.

• Push Button Bonnet Pin Kit: Push button release for cleaner bodywork lines and one hand operation. For carbon fibre or fibreglass bonnets only, since the pin's holding force isn't rated for the weight of a steel panel. Best for modern race and rally cars and faster pit stops.

• Grayston Competition Boot Springs: Traditional spring loaded boot lid stays used to hold the boot open during service work and to keep the boot properly seated when closed. A staple of British rally car preparation for decades. Best for classic and modern rally builds where a lightweight, mechanical stay is preferred over a gas strut.

• Rubber Bonnet / Boot Hooks: Traditional rubber hook fasteners. Best for quick temporary securing, boot lids and spare wheel covers.

If you're unsure which pin type suits your car and event regulations, get in touch, provide your vehicle's make, model and year, and we’ll do our best to advise.
