Help - Restoration of 3.2 Carrera Clubsport

fergus57 · Oct 25, 2016

Hi All,

We are just reaching the end of a restoration of a 3.2 Clubsport and are having a debate over the rear valance (Under the rear bumper) - should it be a smooth gloss paint finish as per the main body of the car, or should it be a slightly mottled finish in the body colour i.e. the same as the rear wing valance adjacent to the exhaust aperture?

I've tried to find pictures of this area and all thus far are not close/detailed enough to be able to tell which is correct, so any feedback/help would be really appreciated.

Many thanks in advance.

Hi Fergus,
The rear valance is smooth. The 'mottled' finish you refer is stone-chip primer under the top coat and this was applied to the sills and, as you quite rightly say, the rear side valance panels.
I can give you more detail tomorrow if you want it.
Hope this helps.

Only close up I could find of my old CS.
Hope it helps

That vertical section of stone-chip protection isn't factory standard - it's been added by an after the car left the factory. A good idea for durability on the stone-throw area, but non-standard.
Is you car right or left-hand drive Fergus? The reason I ask is that a lot of LHD cars had a lower (read 'lighter') standard of body protection to the UK supplied cars.

Hi Chris/Alan,

Many thanks - mine is a UK RHD car that, as far as I understand, previously was used for time trials/sprints

I'm 90% certain the rear valance was smooth - however, the bodyshop are saying it should be the same mottled finish as shown in your photo under the bumper bellows/rubber.

If there is any other 'official' or otherwise detail I can use in my discussions that would really help.

Once again, many thanks for taking the trouble to respond.

The rear under bumper valance should be smooth paint not body Shultz.
I had a never painted car that's how mine was.

My understanding was that one of the areas of attention on the CS was to pursue an ethic of weight saving. I recall reading somewhere about no underbody stone chip protection being applied, and I would expect that would extend to the exterior surfaces as well.
I suggest you have a chat with Alan, the 911 Carrera Club Sport Register Secretary. Find his details in Porsche File or Porsche Post.

ps. The rear valance (Under the rear bumper) - as you mention in your opening post - doesn't have any stone chip protection on my car, not even on the edge. I would confidently say that if the '89 Carrera 3.2 didn't have stone chip there then the CS certainly wouldn't.

PVC underbody protection was deleted on German cars (possibly all LHD European market cars), but WAS applied as standard to GB RHD cars. I think it may have been a delete option on RHD cars, but it was a very low take - I'm only aware of one of the 53 that didn't have underbody protection.
Just to clarify, underbody protection is NOT the same as the stone-chip primer referred to in the original question.
As Charles quite rightly states, there should be no stone-chip primer on the rear valance

Many thanks all.

Bodyshop advised accordingly and we shall have an accurately painted 3.2 CS.

As an aside there was no underseal on my car - just a thin layer of waxoyl, now removed, however given its competition work I'm not sure if this was it's original state.
