Should work according to most of the posts Ive read... why dont you go and measure the car to make sure.
i think that for the rear you will need 4" back spacing. maybe even 3.75". you really need to measure what clearance you have with some current wheels then see what room you have. on mashori's car he has the slightest rub on the inner fenders. ill have to see if i can find the thread with the final dimensions he used.
http://mmb.maverick.to/showthread.php?t=79878 here is the tread on his wheels. he used a 17x9.5 with a 5" back spacing. so off of knowing that he has the slightest rub with a bigger wheel and tire than your looking at your 4.5 back spacing should work nicely.
