Seat Height, Leg Room and Head Room in a 3.2 Carrera

[Hooey]

Hi all.....

I know this has been covered elsewhere, but I could still do with some solid advice on possible solutions.

The 1985 3.2 had higher seat mounting rails than what came before, or after, as they were lowered again by Porsche for the 1986 model year to give extra headroom. This can cause headroom problems for taller drivers and for the use of a helmet. The only good solution with standard seats, appears to be lowering the mounting rails to give the extra inch or so of headroom, same as the 1986 to 1989 model years. The problem is that this involves some cutting, lowering, and re-welding of the bracket rails on the driver’s side. This is a real issue in the US as the plastic fuel lines run down the inside of the central tunnel to which the support rail will need to be re-welded on left-hand drive cars, which has clear safety issues. However, the fuel lines appear to only run down the nearside of the tunnel, which in the UK means they are well away from the driver’s side tunnel wall on Right Hand Drive Cars.

So, my question is, what actually runs down the inside of the Right hand side wall of the central tunnel on the UK driver’s side, on a right-hand drive car? Is there anything that could suffer badly from some heat transfer, if the UK driver’s seat mounting rail (passengers seat in the US) was re-welded to the tunnel wall an inch or so lower?

Has anyone done this?

Any and all info would be appreciated.

Many thanks......

The seat rails on my car are lowered by 25mm, but it was done while the shell was bare.
For a RHD car the main rear wiring harness and the heavy amperage starter cable run down the tunnel conduit inboard of the driver’s seat, so I wouldn’t recommend welding while the harness or starter cable is installed.
My car is a non sunroof coupe and with the rails lowered I have about five inches above my head - I’m 6’2”

Bumping this thread. I have an '85 Carrera too and would love to know if anyone has worked out an easy way to lower these seats down to the '86-onward height?

Thanks in advance!
