Hi guy/gals! pretty new to the whole car scene/forums. just picked up a 2003 350z Performance trim at the start of summer,love the car! looking to get some deep concave wheels for it. I'd like to not do much in the way of body mods to make them fit,fender rolling shouldnt be a problem tho. Ive been looking at Rohana RC-20 and the RC-5. 20x9 +15mm fronts,20x11 +28mm Rear. with the right tire could i get away with that size with too much modification,if any? (future plans of lowering the car at max 1',at stock height for now),thanks for any help,hope i gave enough info.

 

IMO 20's dont belong on the Z. But with the proper sized tires. probably 30's or 25's idk... but the offsets are pretty good. shouldn't rub in the front. i have 19x10.5 +12 out back on my Z. Im running 255's though, but I have seen 285's with just a roll fit in there. 1in. is about 25.5mm. so at 11+28 you are pretty close to the same specs i have. I think you'll be like 3mm further in then I am. So... if im right 285's will need a roll. My offset calculations may be a little rusty... ha

 

This is my old setup... 20x10.5 +15 all the way around. 15mm spacer added to the rear. I had 245/35 tires all around...because low

Your sizes and offsets would work just fine with 255 front 285 rear.

IMO concave wheels only look good on the Z when they are less conservative offsets and a stretch on the tires

 

I run 20x10.5 ET25 on all 4. Front tires are 255/35 and rears are 275/35. Wheel clears the front hub carrier just fine and if it's not due to the caliper, it would have not needed a 3-mm spacer. The rear has massive space, but running zero effective offset proved to need more involvement; quarter panel lip would need rolling and slight pulling.

 

Thank-you soo much for the help/info! greatly appreciated

 

Jose2008Z your Z looks amazing!

 

Thanks! It's for sale! $18k

 

20's are donk status for a z and look pretty out of place. Please reconsider your choice.

 

+1000

19s look so much better.

 

I guess I drove a Donk then...

 

I would like to get 19's.... but i cant find a set of black,concave rims with a nice offset,at a decent price. The Rohana RC-20 are 1,600$ for staggered set of 4(without tires)

 

I believe the wheels I had on my car come in 19 x 10 now

 

Plenty of wheels can be had at that price range. Just go look at the 19 inch wheel thread.
