Personally I would have gone with P45F for the front and P45R's for the back (as I like the depth in the P45R's for the rear but prefer the P45F's for the front). But that's just me. You should see if a machine shop can make some center caps with a cover plate to cover the lugs....then they'd be perfect. Also it's good to see what a 18x9.5+30 looks like on the front and rear.
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
