Every Porsche in for servicing and tuning at JZM goes through our bespoke health-check inspection as standard. We’re always happy to go through the report with you afterwards, the more you know about your car, the better.
Porsche service
Our original Porsche servicing and diagnostics equipment is probably the most comprehensive collection in the UK. JZM were the first Porsche PXN (Porsche eXternal Network) independent specialist in the UK and have always been updated up to the latest PIWIS Ⅲ. We also have a direct data and comms connection to Porsche HQ.
Porsche tuning
JZM’s extensive tuning experience comes from the knowledge of what works and what doesn’t. We are enthusiastic yet realistic refiners of Porsche only recommending and fitting the best bits – tried and tested parts that really work. Manthey Racing might be considered at the pinnacle of Porsche tuning, we’ve been approved fitters since 1999.
