tuned suspension? the xpackage comes with the sports tuned suspension, low profile tires, bigger rims. my concern is: will the ride be noticeably more bumpy, and with the low profile tires, will the car be noiser and have more vibrations? also, with low pro tires, will it lose traction when it rains? is getting this xpackage better than just getting the standard IS model?

wait for the chevy camaro coming up in the fall of 07...lets talk about real cars, American cars

low profile tyres make the car more bumpy and are hard on the suspension
