Rim Size for 1997 Boxster

Key would be to ensure that the 18" tire/wheel combo had the same or less weight, along with same diameter/circumference, as the 17" setup.

If these conditions are met, the suspension should be loaded similarly between the 17" and 18" setups.

I believe the main concern was increased torsion load from the reduced sidewall height & presumably higher performance tires.

I've just checked my VIN number as i knew it was a late 1997, I think mines ok for larger rims as the number is

WPO ZZZ 98 Z W S 6 ****

Am I right in saying that my car is a 1998 model? I have the original bill of sale for 28/11/97
The bill also states that the order was placed on the 26/09/1997 so there was only a 2 month wait for a new boxster in the UK back in 1997.
