97 to 98 changes

Rear body structural change included redesigned wheel wells and coil spring mounts, lower engine compartment bulkhead, rear wall cross-member and rear axle mount reinforcements.

Doesn't sound to me like Porsche thought just lighter wheels was the solution as this was to allow 18" wheels, not 19" or 20".

Other downsides of larger diameter wheels are the cost of tires and the increased risk of something penetrating through the tire and destroying the wheel.
