As industry leaders in a field with zero margin for error, we take quality very seriously indeed – not just because our reputation depends on it, but because our customers’ safety does. And as accredited suppliers to prestigious OEMs, we have rigorous systems in place to assure it.

Ours is a culture of attention to detail, and we use the most advanced coordinate measuring machines and laser scanners to verify the integrity and accuracy of every item we produce.

As you would expect, all our race engines and gearboxes are fully tested before delivery. Gearboxes are run on a dedicated test rig, and engines on one of our in-house dynamometers, the largest of which can handle up to 2500bhp to cope with the massive torque loads of the most powerful prewar units.

With Crosthwaite and Gardiner, racers know that nothing is left to chance.
