Has anybody had experience with pcd wheel spacers?
I wonder if these are to allow wheel studs to be spaced out different to the standard fit and therefore allowing different styles/types of wheel to be fitted?

Never heard of PCD wheel spacers. PCD is pitch circle diameter & is the dimensions of the stud in terms or distance from centre & number.
Do you mean variable or slotted spacers? If so they are fine as shims but I wouldn't want them beyond 2-3mm.

They are spacers which I believe allows you to have different stud pattern to the normal ones.
I thought that they may allow a different choice of alloys to the usual ones maybe?

Ahhh PCD Converters. TBH wouldn't be my choice. They're quite common on VW especially Beetles to allow a wider variation of wheels, not convinced I'd want them on Pork though. The longer wheel studs would result in much greater loads on the suspension & wheel bearings. The other point is that Pork wheels are hub centric, in otherwords the studs support the wheel but the wheel centres on the round bearing protrusion of the hub itself. If you run very wide spacers or adapters say 15mm or above then you'll lose this alignment & start to rely on the studs alone.

They worked fine for me on my Seat Leon with D90's on. The Leon was 35mm offset and the wheels were 55mm so I had some 20mm thick spacers made up. They had 10 holes in, 5 at 100mm PCD to bolt them to the hubs and 5 with studs in to bolt the wheels to. Loads of the VW crowd use them and the only problem I've heard is when the centre bore doesn't fit the hub correctly. H&R make loads, different thickness and PCD's. I've never seen any to fit the Porsche hubs though.

i used a h&r set to fit merc pcd (5x112) BBS RS to my old corrado (5x100).

the adapters bolt to your hub, your wheels bolt into the adapter. usually about 20mm thick.

these days i hear it's possible to get adapters to fit almost anything. as stated above it's a really common thing in the VW world, i think there is an engineer based in manchester who custom makes these things for reasonable money. if you want me to track him down give me a shout

Just spoken to someone who had a set of 55mm thick spacers made for the rear of a Mitsubishi Starion at Pemberton Tyres about 8 years ago.

While I'd share Jim's caution a little and I agree with the hub centric comment (aren't all cars like that anyway?) I think it should be quite possible to have a custom setu make that fit snugly around the hub centre and present a new centre protrusion to match the centre-bore of the wheel being fitted.
