JMG only install parts which are sympathetic to the design philosphy of the original Porsche design while the part also being a noticable improvement over the original parts. We would like to think that if the original design engineers at Porsche were to inspect your car with our parts installed they would not only approve of the parts as an improvement but may also believe they were from the Porsche motorsport division.
To improve your Porsche, call or email us today to arrange any of the above modifications or to discuss your requirements. Tel: 01202 488800
JMG PERFORMANCE MODIFICATIONS SHOULD NOT DEGRADE THE RELIABILITY OF YOUR CAR, HOWEVER SHOULD YOUR CAR HAVE A COMPONENT WHICH HAS AGED OR WORN ITS LIFESPAN FOLLOWING MODIFICATION OF THE CAR MAY BE REDUCED
