996.362.142.03 rears. 295X30 -- offset on this wheel is 45 mm -- you need 63 mm to 65 mm on the rear.

996.362.136.04 fronts. 225x40 -- offset on this wheel is 50 mm -- you need 50 mm to 52 mm on the front -- so these are ok.

Loren, how did you get the operating range for the offset? Is this just an industry standard?

TSBs. Both Summer and Winter Wheels and Tires TSBs specify approved wheel widths, diameters, and offsets.

As a Contributing Member you have access to the TSBs.

Loren, Can I use a 18"x 8.5" 40 offset on my 2001 C2 narrow body?

Porsche does not recommend anything over an 8" wheel for the front - until MY2002.

In 2002 they said GT3 wheels 18 x 8.5 et 40 mm were ok.
