18's on a 370z

josemartinrea · 02-08-2015, 11:21 AM

daaaangit. I'm trying to get some apex arc-8s. ~$1200 for 18s under 21lbs seems like I steal. I just hope they take custom orders. What would be a good offset as to where I have a maybe a finger's worth of gap between the tire and the wheel well?

RPF1s are awesome, there's a reason they sell so well and are on 1/2 the cars at any given track day.

Are you talking about the gap outwards or the gap from the top of the tire to the wheel well (for which aspect ratio will matter, not offset)

josemartinrea · 02-08-2015, 09:38 PM

Outwards gap. Scott@synergy's gap looks fine. Would +12 look okay as well? I think I have the ratio covered. I'm running a tall tire and a swift spring drop.

Gaps gonna depend on camber too. Mines -1.5. Zero would close the gap a lot.

If your're interested im selling my 17.4lbs fronts! If you buy rears like I said you'd only be at less than $1200 for a way lighter wheel.

josemartinrea · 02-09-2015, 06:34 AM

Hmm. I'm still in the process of deciding which wheels I want to get. But I will def PM you if I decide on the rpf1s! Does curb rash come free with them? Haha

josemartinrea · 02-09-2015, 06:37 AM

Oh wait they're 19s. I'm looking for 18s. Cheaper tires and more variety. Sorry! BUT. I do know someone looking to put light 19s on his 350z. I'll def let him know.

Was this for me? I have 18's

Can someone make a recommendation for me? I'm getting the Forgestar F14 18x9.5 front and 18x10 rear. What offsets should I order for a *close* to flush fit (not exactly flush, but just close to it). I'm planning on running 255 40 18 fronts and 285 35 18 rears. If I stay with the stock 9" width for the front wheels, the 255 should still not be a problem, right? I cant decide b/t going up 1/2" to 9.5" or just staying at 9". Let me know what you guys think...

Well my friend!!! i dont have 18"wheels but basing on my wheels set up I have 19x9.5+12 front and 19x11+15 rear... love how it looks the car with those offset... and if im not wrong the same wheels that i have but in 18" comes with the same offset 18x9.5+12 and 18x10.5+15... looks flush and really good in my opinion....

BTW my rear tires are 285/35/19 and works with 0 issues...

I hope someday to buy some 18"

Thanks. Do you have pics of your car? I'm sure the wider tires would fit both front and rear. My question was should I got up to 9.5" in the fronts for the wheel width or stay with 9". Any advantages/ disadvantages? The one small disadvantage is that the 9.5 weighs half a lb. more per wheel than the 9". But there should be less sidewall flex under load for 9.5"? Cant decide...

Go 9.5+. I was and now I'm 10.5. I run a 285 and one day I'll even go bigger. I've got some 17.4lbs 9.5's if interested. The car can handle a lot up there so don't down play it only to be disappointed down the road. 255's to small, just run square in the tires and try to run square for the wheels.
