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 scale, at JMG Porsche we can install a Turbo conversion (in development and testing phase at time of press) or installing a custom built 4.0 Litre engine.

JMG Porsche have also been known for some time for offering stealth speaker upgrades, to replace the original Porsche oddball design speakers with off the shelf ones using a unique speaker adapter kit.
