I suspect the noise is just the brake pads moving slightly within the caliper. Probably most noticeable if you reverse, brake then apply the brakes as you move forward.

Have it checked out but from what you describe that sounds most likely and nothing to worry about.

loose top mount or arb drop link...

Ok guys, let's not ruin an entertaining thread with another pointless argument.

The noise is caused by the car being outside

Bought the car without a warranty. The noise has only come on in the last few days. Pretty sure it's nothing serious and 911Virgin wouldn't have found it during a routine inspection.

You'll need to jack up both sides to check for the droplinks. Try replicating the noise whilst braking ever so slightly - if it doesn't do it then, it's the pads (or the discs if you run a floating set up/conversion).

Not being silly or anything: Do check the boot and under the seats for loose stuff... I've seen people stripping cars because of golf balls that went awol...

Well, as often happens with these sorts of things, the knocking noise that we thought was from slightly worn monoballs in the top mounts has gone. Completely gone.
After the blast across north Wales with Mike and Ade the other weekend the noise disappaited and disappeared.
There is still a bit of play in the O/S damper that was noted on the report that came with the car from Chris at Centet Gravity and the dampers are probably due a rebuild soon, so after the summer the car will get some fettling.
As another note, while the car was up on the ramp at Sports and Classic we saw that the Powerflex bushes on the front arms were getting chewed up at the ends. When the dampers are getting rebuilt we'll replace these with solid units.
First addition to the car is going to be a set of RS29 front and RS14 rear Pagid pads as per Fiorino's recommendation. Again while on the ramp we could see that the inside pads (standard P90 pads all round) were much more heavily worn on the inside of the disk than on the outside. They will definitely need changing after the next track day. Which will be an Evo track evening at Bedford in June.
I've also arranged to get some alcantera cushion covers made for tr seat base and back. Just to prevent sliding around in the seat until I decide if I'm going to get a half cage and harness fitted.

Oh, and thanks for the jack recommendations in the other thread. Ade (keep it lit) has a Snap On one on order for me.

Loving the car, by the way. 1650 miles done since collection. Sat outside right now covered in tree pollen. Oh the shame of it.

Over 2000 miles in now and looking forward to Bedford on Friday evening with a load of mates and the Evo boys. Should be fun.

Also just fitted my first upgrade yesterday. I've had some cushion covers made for the base and back panels to prevent me sliding around too much on the seat when on track. Plus it'll keep the leather pads nice and tidy for later on.

The amount of underseal on mine was very serious :-)

There's more now. I'm far more concerned with keeping the underside clean than I am with where it lives.

Great car, OP. I'm with you and the other posters above who say they should be used and not just polished. As far as I know there's no way to make them sound fantastic without getting them out there and going for a blat. They don't make much noise in a garage.

I'm taking mine to Poland next week (via the Alps) - will see how it likes 4k-odd miles in a week. Woohoo!

Great article in this month's GT Porsche magazine -- nice write up !
