Can anyone tell me if there are any performance/handling differences between 18" and 19" wheels on a Cayman "S"? Thanks.

 

Yes the 18" are preferred on the Track to 19" also depends on the Tires as well . some Cayman owners use 17" or 18" wheels on the track and 19" or 20" for the street.

 

it all depends on your suspension and tyres as to what will work best

 

The previous owner of my car had installed the nineteens.
I haven't compared the 18 vs 19 wheel size with the same car and tires so I cannot speak for performance or handling comparison, but the visual of the larger wheels is gorgeous. Have a good one!

 

The 'R' has 19" wheels. Does that matter?
