Im looking into purchasing wheels for my Z. i was wondering what everyones personal opinion was on what looks better on a Z, 18s or 19s. also the width of the rim...front-8.5 and rear-9.5 or front-9 and rear-10?

 

19's look pimper and fill out the wheel wells nicely
18's are more practicle. (less mass, cheaper.. more rubber protecting them incase you have ****ty roads like I do around here)

8.5 front 9.5 rear are the most typical setups for rim widths
245 front tires, 275 rears for tires

You can go wider but then you have to start looking at the possibility of rolling fenders and stuff. (depends on the rims offset, width and rubber size)

Your best bet is to figure out what you need, look up other peoples rides in the tire/wheel section and figure out what you'd prefer.

 

Looks= 19's
Practical=18's
Personally= 19's

 

I personally think that the look of a 18 or 19 don't look that much different. I really think that the tire width gives the Z the best look. Just look at a 305 tire on the rear looks so much meaner than a 245!
