JWM has 3 distinct lines of business:

Aftermarket for supercars, high performance road cars, track cars and race cars. We offer a wide range of suspension upgrades, working with brands such as Nitron, Ohlins, Intrax and KW - often helping with the development of new products. Our other successful line is our exclusive range of LiFePO4 ultra lightweight batteries, which are approved for Motorsport UK and FIA events. 

Suspension, Setup & Race Engineering We provide services at out Brigg workshop in chassis setup including geometry and cornerweighting.  We offer a consultive approach setting cars up to driver use cases, and not factory settings based on our race engineering experience in series such as BTCC, British GT and Ferrari Challenge. We also have our own shock and spring rate dynos in hour to aid development, and allow us to service or revalve your existing damper units.

Servicing & Diagnostics We have recently started offering servicing for owners of McLaren, Lotus and Caterham cars from our North Lincolnshire workshop. With deep expertise across all three marques, we’ve invested in advanced diagnostic and servicing equipment—including full McLaren MDS diagnostics—to ensure your car receives the highest standard of care.

JWM is based on the foundation of experience and knowledge, so lacking from many businesses which to many look the same. Our approach to the market is based upon research and a proper understanding of motorsport you only get from degree level education and working with engineers and drivers at the top of their game, whether that be design or trackside engineering. 

We endeavour to keep all items (excluding those manufactured to order) in stock and offer next day or 48hr delivery depending on the time of day your order is received.  All deliveries are reliably shipped in partnership with DPD or overseas with FedEx or UPS.

Everything we sell comes with a minimum of 1 years warranty and everything we do is fully insured. 

For some parts the diversity in size and weight of some parts means we ask that you email us so we can calculate the best insured shipping rates.
