RS2 Cups size and ET?

[Coxy]

I should know this but want to be 100% sure.
Does anyone know the correct size of the RS2 cups.

17 x 7.5 et ??

Isn't it 17x7J on the RS2 ?

Doubtless we'll be corrected soon enough... I definitely can't remember the offset.

I do know the PCD is 130mm though on the RS2 wheels - Porsche hubs, as opposed to Audi ones.

Apologies, you are right, 7j x 17". I've got a set on my van which is the unit next to me at work but can't read the darn e.t. and can't find it anywhere on the net!

Offset is something like ET52 IIRC.

[Nuvo]

ET52 was the figure I was thinking of too. Nope it's 55 .

[Jas11n]

Correction, just checked FA and it states ET55

Will any Porsche wheel bolt up to the RS2 hub? (not necessarily fit under the wheelhouse). What is the diameter of the wheel centering lugs where the wheel fits on to?

Thats PCD of 130mm which I posted earlier....

There's a 1mm difference between the hub on an RS2 than that of a Porsche.

Porka rims need the centre boring by 1mm out if going onto the RS2.

So if I had the RS2 hubs turned down before I installed them into the wheel bearing/hub carrier I would not have to modify the Porsche wheels, yes?

Yes I have been told that before. It is difficult to build an Ersatz RS2 coupe from across the pond. Lots of questions but thankfully alot of helpful information to be found on this forum.
