Recently I installed HR Sport Srings on my 03 911 Carrera. As a result, now the front of the car is 1/2 inch higher than the rear. I'm presently running the OEM tire setup (Frt 225x40x18 -- Rr 285x30x18) QUESTION: Is there any potential road compliance problem if I replaced my front tires witha 225x30 or 35x18 setup Thanks!

Not sure how long it has been since you installed the HR Sport springs, but it is not uncommon they will settle over a week or two and you may find the difference may change. I would wait a bit before making a tire size change for compensation. Have you spoken to HR to see what they say about the ride height change??

Good Luck!! Demosan

Thanks for the relies gentlemen.   The HR Sport Springs were installed 3 months ago.  But I will follow your recommendation and contact HR. Perhaps they can provide a solution.  The reason I posted this question was because I was advised by a mechanic at the dealership ... changing the OEM tire setup would negatively affect the car's road compliance.  Again, thanks for your advise I'll let you know how I made out........
