About GWR Motosport

Providing Expert & Honest Service For Over 23 Years

Our History

Having worked on every day road cars from 1980, GWR Motorsport was formed in 1997. When we started to build a quantity of engine management wiring harnesses for a local after-market ecu manufacturer, a move into new premises was needed.

Expansion into data logging and chassis systems meant larger premises. A few years later it became apparent that we needed larger premises again, a 3rd move and it’s where we are today.

Our Service

As a company we offer a bespoke wiring harness design, manufacture, commissioning, and support, including a range of high-quality sensors from top tier suppliers.  Associate this with our other services of injector testing, ignition coil testing, advise and support, GWR Motorsport can be your one stop shop for motorsport electronics.
