The following pages contain extracts from the ‘JMR Performance Guide for the Aircooled Volkswagen’ and other good stuff. You’ll find plenty of technical information and advice regarding improvements you can make to your aircooled Volkswagen that you won’t find elsewhere. This info and advice is based on years of experience, building and testing numerous combinations of parts. I’m sure if you follow the VW ‘scene’ to any extent, you can’t fail to have noticed the ‘John Maher Racing’ name crop up regularly at the track, on the road and in the VW press. By the time you’ve looked through these pages, I hope to have given you an insight in to the quality and extent of work carried out at JMR and you’ll also have some idea of the amount of investment, in both time and money, I have put in to the business in order to offer you, the customer, the best possible service and quality products available.

An important distinction between myself and others offering parts for sale, is that I actually use the parts I sell. I will not supply parts that are not up to the task in hand. So if you want to buy a chrome generator pulley, see through distributor cap or ‘slip in’ 1679cc piston kit, exit this site and look elsewhere. But if you want to spend your money on parts that will enhance the performance of your vehicle, precision machine work or a complete engine and transmission package, go to the contents page and read on.

Numerous JMR equipped cars have been featured in publications such as Volksworld, Hot VWs, VW Trends, Flat 4, VW Motoring, Street Machine and many others.
