I would like to get the Falken Koblenz rims in gloss black and a polished lip for a 2002 cavalier. The 18" rims do not come in the correct bolt pattern, but the 19" wheels do. I have had one shop tell me they would fit and another shop tell me that they wouldn't fit. The car will also be lowered using either the Eibach Sportline springs and AGX or the RKSport coilovers. The car is getting the RKSport type J kit put on right now and I would like to have wheels to accent it when it is finished... nothing like putting all the money into a body kit and using the stock rims.

Will a 19x8.5 and a low profile tire (probably a 225/35/19) fit on a 2002 cavalier without modifications to eliminate rubbing?

get a 215/35/19 tire and find out the offset of the wheel. if the offset is 35mm (which would probably be the best for that wide of a rim) then there is a good chance it will fit but it will stick out like 3/4" from the fenders and you will probably have to roll your fenders
