Modification

The engineers at Porsche made an awesome job of designing your Porsche to be your very own ultimate driving machine.

However, like any car model, it was designed to appeal to a wide audience, across many demographics and nations each with their own regulations or requirements.

Sometimes what you would like from your Porsche will differ from what Porsche originally intended. Perhaps you would like your Porsche personalised, or maybe you would like it to be more powerful, corner faster, have improved audio or even a different interior. At JMG Porsche, we can make your Porsche dreams come true.

Another form of modification we like to think of as evolution. As the years pass since your Porsche was manufactured some design defects come to light, reliability issues are discovered and improvements engineered. As well as personalising or improving your Porsche, we can also perform modifications which improve reliability or service life.

In this section we will explore some of the possibilities available for your Porsche. If you would like to read more about Porsche modification, please visit our articles section. If your modification is extensive, perhaps your car could be booked into our special projects division, where modification is bespoke and anything is possible.

Boxster & Cayman

Written by
Your Boxster or Cayman modified to your requirements. The Boxster and Cayman benefit from excellent weight distribution, which with just a little more power allow them to run rings around the more expensive Porsche models. This is probably why the performance from the factory was limited to the levels these cars were sold with. JMG Porsche modification to these models can be as simple as retrofitting options not fitted to your car, such as cruise control, on board computer, or even a child seat airbag deactivation kit or clear indicators for an early model. At the other end of the…

Modification

Written by
The Porsche factory designed your Porsche to be all things, to all people in all conditions. However your Porsche is your Porsche, used the way you use it, in a much narrower range of conditions. Porsche designed your Porsche to be driven by anyone from a grandmother using it for shopping, through to a race driver on the Nurburgring. They designed it to be driven using the poorest quality of fuel available in the deepest darkest parts of Africa, as well as the best control race fuel the world has to offer. To be driven at sea level, as well…

924

Written by
Your 924 modified to your requirements The Porsche 924 originally started life in the 1970's as a 120 BHP car, sufficient for the day, but with excellent weight distribution and therefore balance and handling. Later Turbo, Carrera GT, GTS and GTR versions had varying levels of performance and handling increases, components from which can benefit lower spec or earlier cars. At JMG Porsche we have modified 924's, 924 Turbo's and Carrera GT's to various levels of tune and race prep, beyond the scope of any of the factory models. Unfortunately few people realise the potential of this car, which are…

944 & 968

Written by
Your 944 or 968 modified to your requirements The Porsche 944 and 968 were an evolution from the original Porsche 924. With great handling potential due to their weight distribution, these Porsche are known for having a chassis which can handle greatly improved Performance. The 944 Turbo was a model which had its performance held back by the Porsche factory. As it stood, the Porsche 944 Turbo was faster around many tracks than the more expensive Porsche 911 Turbo flagship model, and the 968 Turbo S and Turbo RS models were limited in performance and production numbers for the same…

928
