Once upon a time, a young man dreamt of owning a 993 so he saved and saved until he had enough pennies to buy dream car, he found the perfect 993 C2 Narrow Body and purchased it on the spot.

Problem, young man start spending money to improve the look, so out went the all the stand spec lens and replaced with clear lens, exhaust upgrade, sound pack, etc.

Never happy with the 17 cup alloys, he decided to buy some 18 Turbo look alloys. Then the nightmare begins. OFFSET!!! rule.

The book says offset (ET) = 65. The wheels Ive purchased are ET= 52.

Will they fit? some supplier say they do and other say they wont. I tried them on my car and they seem ok, but the wheel arch is flush on the wheel edge, concerning the outside of the tire will rub against the arch.

Any suggestions, I hear a few sites offering offset adjustmentis that recommended/safe?

As anyone experience this type of service?

Lets hope this story has a happy ending, which doesnt cost me a fortune!

Without getting too technical, incorrect offset will alter suspension geometry, which in turn will effect how a car handles. I would suggest going to a specialist with expert knowledge of suspension set up like Parr or JZ Machtech.

If you have ET52 offset rims front & rear then you have Boxster rims (as per Peter's post).

Further to my post, altering wheel offset only becomes critical to geometry on the front (ie with regards to steering), although you may find clearances issues on the rear.

Altering the wheel offset will effect the steering axis in relation to the tyre contact patch. A difference of a few millimetres can be enough to alter the offset from negative to positive with inherent handling issues effecting steering feel and self alingment. However, as the fronts you have are the reccommended offset then all should be fine & dandy.
