Wheel offset

[Big Les]

Does anyone know the standard Design 90 wheel offset on the 944 S2 Cabriolet - are the front and back both 52.3 mm or 55mm, or the front 55mm and the back 52.3mm?

Front ET55
Rear ET52

just went out with a torch and checked what was stamped on them. []

Many thanks for the info.

Do you know if it make much diference if a 52 was also used on the front, if it fact fits at all - ie 7J x 16 52 (instead of 55) front and 8J x 16 52 rear?

7J ET52 on the front will be fine.

Thanks Paul - a handy calculator. I will have an extra 3mm offset outwards.

Will it make much difference to the handling (for usual road use - no track days!) if the front has a 6J 52mm offset? Using the calculator above it would seem to be 16mm more clearance on the inside and 10mm less width on the outside edge. Any opinions?

951/952? What is the difference? 952 is the part number prefix for unique Turbo RHD parts. All 944 Turbos are 951s whether they 23.3mm offset, 52.3mm offset or later 250PS models.

Its hard to give you an accurate answer when the vendor hasnt given you a proper answer to your question.

Presuming that the fronts are ET40 then they will fit, but 9" ET16 rears would only fit inside a widebody aircooled 911s arch!

Unfortunately spacers are only able to help where the wheels are too far in. These are already way too far out.
