Porsche 993 Cup 2 wheels
 

Hi All
New to forum, based on the Sunshine Coast, Queensland, Australia
Purchased a lovely 2004 Boxster, Silver. 2.7 5 Speed for youngest son
First car, but has been learning to drive in our 981 Cayman for 12 months.
He loves the Boxster, we all do.
We have a set of original 993 Cup 2 wheels 17 inch.
Look beautiful on car (Having restored them) but noticed a slight scraping on Left hand rear when driving.
Cannot see where it is scraping. Need spacers?
Front rim offset is 55mm which match factory spec.
Rear rim offset is 48mm/50mm (Factory spec) Cup 2 wheels are 47mm
Any clues?
Pete
