Wheel Fitment Confusion... 2003 C4S

[spender]

I have a line on buying some winter wheels for my C4S - they are on some Victor Equipment Lemans rims, sized as follows:

Set of 2: 18 x 8.0 Victor Lemans - Front

Set of 2: 18 x 9.5 Victor Lemans - Rear

On the face off it, they should work - the tires they are carrying match the sizes in the C4S owners manual. However, I am totally confused about offset.

The front wheels in the manual say they should have an offset of 50 mm - the front wheels here have 45 mm - does this mean I need a 5 mm spacer?

On the back wheels, manual says (with 10 inch rims) that offset should be 47, but these are 49 - is that extra 2 mm going to make these rims not fit?

Any help would be appreciated! Thx

Look at Victors website, They have a fitment link. It will telll you wether they will fit without spacers

The rear wheel will be 2mm closer inboard than is "ideal" according to Porsche. More than likely, this will have zero practical effect. If needed, you can always use a thin spacer to push the wheel further outboard.
