hey rominl...i was talking to my friend and your right i should just go with 20" since the tire size are about the same and 20" tires are actually cheaper then 19"

so what is the ideal offset i should get

front 20x8.5 and the rear 20x10...thanx

 

I would go with 20x9 front and 20x10 or 20x10.5 in the rears. I spoke directly to a wheel MFG and this is what they suggested for this car. I wanted to do 20x11 in the rear and they suggested to not do that on this car. I went with what they said to use so will see. are you going to shave the rears or not? If you are going to shave the rears I can tell you what I was told where options to help you out. PM me if you would like

 

yeah depends on what you want and how much you are willing to do on the fenders. how about tires, stretch a bit or not?
