So, I am a newbie to performance cars. I have wanted a Porsche since the late 1960's when I had a Karman Ghia and was thinking of putting a used Porsche engine in it. Over the years I have put up with family vehicles, including the emasculating mini-van.
But now I have my 2000 Boxster (for only six months now), oh happy man. The car came with 17" factory wheels that I put new Michellins on less than two months ago. I recently found some aftermarket Carrera 18" wheels with Falken tires, on ebay, and got them.
I just put the new wheels on today and they look great. I took it for a ride and I could tell a number of differences between the new and old wheels and tires, but what I seemed to notice was that the car did not seem as quick. As I understand it, my new tire/wheel combination should only add about 3 lbs/wheel of rotating mass to the car. Should you be able to feel a difference in the ability to accelerate quickly with 18" wheels compared to 17" wheels, thanks,
Ed
