What is it?

Looking at the underside of my sills with the car in the air at the body shop there is a square protrusion about an inch deep towards the rear of the sill. About the same size as the jacking point. It looks like a drain point but is it?
Could it come off?
Its the only downside to running without sill trims as it breaks up the smooth line. It would otherwise be covered by the trims.

I don't think my sills will be too bad but for anyone who hasn't investigated the mounting points of these trims on S2s and turbos I advise you to do so. The really do trap all the rubbish and rust will start here and cause untold issues.

Yes, not the best design feature ever. I guess it shows an overconfidence in galvanising. I have seen a 944 Turbo in the car park at work with the sill trims removed and it looked OK - the square jacking point didn't stand out, I guess if you know it's there your eyes will be drawn to it. I guess you could trim the square jacking point down a bit so it doesn't protrude so much.

When I first took my sill trims off I was uber aware of the centre jacking point!!! To the point that I was adamant I would cover it up with something. Nearly a year later I hardly even notice it. I am in the process of painting and undersealing the whole of the underside of my car (albeit a little bit at a time) and I plan on painting them black. Hopefully this will make them even less noticeable. Will let you know how I get on and maybe post a pic.

Yes, each is fixed with a screw and nut. When they come off easily it means there isn't yet too much rust in there.

So is it a 2nd jacking point? If it is I didn't know about that. I don't mean the round jacking point in line with the diamond on the sill but a square piece the same size but much further back towards the rear wheel.

No mate the one by the diamond is the jacking point. The ones that are fore and aft of that one are your lifting points for a four post lift or where you should put axle stands. You should only ever jack from the centre post.

Thanks Rob, I'll just paint it black then along with everything else underneath.

That's my boy!!! Exactly what I am doing at the moment. Lot's of black hammerite and a few gallons of waxoyl. To be fair it should look pretty nice under there by the time I have finished.
