Scott Gardner Job Title Gold Diagnostic Technician Place of work Porsche Centre Bournemouth, UK Time at Porsche 12 years I’ve a 964 C4 (it’s my first 911) and am getting very frustrated by the understeer induced from the heavy all-wheel-drive system. I’d like to know therefore how easy is it to remove drive to the front wheels, effectively converting the car to rear-drive, C2 spec? I’m sorely tempted! Ray Endsleigh, via email

Scott’s answer: “This would definitely not be something I would advise doing to a 964 Carrera 4 – they have too complex an all-wheel-drive system with the high pressure pump and diff locks. Speaking to our classic car technician, Nick Perry (also Gold certified) he mentioned that even for installing a Carrera 2 gearbox, you may potentially still encounter problems with the diff lock system.

My advice in the first instance then is to opt for a good geo setup to help eliminate some of the understeer you mention or, if you are really committed, sell the 964 Carrera 4 and look to replace it with a reardrive Carrera 2!”
