Default 20" Rim Question

I have an opertunity to get a smoking deal on a set of used rims that are in ment condition. My question is will 20s purchased for an 03 fit on my 08. Someone was telling me there is an offset difference and they may stick out more. Does anyone know for sure?

Should fit fine. Are you lowered? Plan on lowering? Whats the width and backspacing/offset of the wheels?

the gmt 800 had a 18mm offset. the gmt 900 have a 30mm offset. This means the rims will stick out about 12mm or 1/2". They should fit fine
