Please Note: Before fitting a LifeP04 battery of any brand you should ensure your charging system is in good order.

Also ensure your battery is positioned sufficiently far away from very hot engine components such as exhaust manifolds. Be aware the digital display should be switched off when not in use to prevent battery discharge
I've been around Caterhams as long as I can remember. My Dad has something of an addiction to these cars, and since the age of about 8 I have been part of his habit, helping work on and latterly designing parts for his and my own car.
Now I'm at Oxford Brookes which is arguably the best university for prospective F1 engineers, with the aim to become a race engineer in top level motorsport.
My journey so far has seen me working on suspension analysis, research and design at one of the most successful Caterham race teams DPR Motorsport who are based close to where I live.
I've also been team lead on Vehicle Dynamics at Oxford Brookes for Formula Student.
The objective of Jack Webb Motorsport is to grow a business which can support my university fees and costs, and also build a name Caterham owners can trust to deliver well executed high quality products to enhance their cars.
I endeavour to keep all items in stock and offer next day delivery on my items in partnership with DPD.
As JWM is a small company, we do not charge VAT.
Please note if you are outside the UK and EU you can still buy some products from me, but the diversity in size and weight of some parts means I ask that you email me so I can calculate the best insured shipping rates.
