Stock Turbo wheel offset?

Anyone know the offset of the stock Turbo wheel? I'm trying to make a decision on a lightweight wheel replacement.

+1 on 56/51 for the 997.1tt, but I've been told that 45 front 40 rear will fit perfectly without spacers. Can anyone confirm?

I suppose it would be like putting 11mm spacers on stock wheels.

Thanks for the info, I searched as much as I could but I figured 6speed would be a more reliable source. Thanks for the info where to access!

couple of the wheel companies i spoke to said try and keep the offset not to far off from stock... those offsets might be too aggressive on the turbo...

Considering that I have the Champion Intercoolers which are closer to the rear tires than stock I.C.'s, is it not better that if change wheels that I select an offset that will give me more clearance?
