I have 3 Grand prix wheels sitting around and threw them on my maxima to see what they'd look like. I know the bolt pattern is 115x5 but i've read they should work without any issues. I wish the offset was better but they don't stick in to far. I can always get spacers. They clear my 6 gen calipers. Here's some pics. If i decide to put them on i'll have to paint the pontiac centers, maybe even the entire wheel (Dark Bronze?) and get tires that are the right size of course.

 

i like the oem bro looks much nice just my opinion tho.

 

stick with stocks unless those new rims are like 5lbs
