I know the bolt pattern is 5 x 114.3, but I need to know the offset so I can see if some rims I am looking at will fit. Also, will 20 inch rims fit on this car w/out a spacer or lift kit. I would prefer anyone to tell me from personal experience. ( not i saw one w/ 20's ) How will the car ride afterward?

the offset is 42... not sure about the 20's.

you can go to tirerack.com and see what different wheels will look like on your car. Make sure that you don't change the outside diameter of the tire too much or the speedometer will be way off. You should be able to fit 20" on there with the right offset.
