I would get the 19s, cheap wheels, cheaper tires, better ride quality and 19s look great on a Z, plus they are lighter

 

go with 20s it feels the wheel well up the nissan dealer told me my 20s ride alot better than my stock 17s thumbs up for 20s

 

Ok, base on most of your recomendations I have decided to go ahead with the 19" wheels. Thanks for all of your suggestions! Now, I have a local wheel shop by the name of Good Roads A.K.A. Groads. And they make their own wheel brand called "Status Wheels."

I am particularly fond of the "R-278 in Hyper Black - 19 wheels." See the following attachments. They are giving me a decent deal on some Nitto's Neo-Gen tires and the wheels, mounted, balanced, locks, tax, for $2,000. They claim that the wheels weight around 19 lbs, which compare to my stock wheels they are a lot lighter considering the differences in size. What do you guys think>?

 

Its begining to sound like the more sensible choice for me to go 19". Although, I may have to get an Eiback Pro Kit to close the gaps.

 

nice enough wheel but sorry, that wheel does not weigh 19 lbs. Lame that they would claim that

 

I'll be giving them a call again on Tuesday, I would like them to be certain on the weight instead of guesstimating. I will find out for sure, even if I have to bring my own scale to their shop. Thanks for looking out!

 

Go 19 man Bc I went 18 and now im regreting it

 

Would you like to elaborate on what you are regretting?

 

or if you search, you can find what the weights are...its been posted on this forum before

I have had both 18 and 19's - both were terrific. The equalizer is the tires - they make or break ANY other suspension related mod you do (wheels included)

 

That 19's with a drop looks AMAZING. Not saying that 18's dont just saying that extra inch is more aggresive for me.

 

19's at the largest. like they've already said....unless youre going for the ganster look... stay away form the 20s. its a sports car : ) get some sport wheels

 

Thanks! So far I gather this much information, I took the back and front wheels from my car off to determine their weight. unfortunatly, my car came with the nissan upgraded Chrome Wheels, which I hate.

Their size are as follows: Front size tire with the wheel weights 49lbs and the back tire with the wheel weights 50lbs. The specs are: 245/45/18 - (B) 225/45/18 (F)

From the information that I gather from the forums ( I search all day) the Ruff Racing/ R 278's wheels weight as follows: 245/35/19 (F) 26lbs & 275/35/19 (B) 28lbs and from checking the Toyo.com website I got the weight of the tires as fallows: Toyo T1R's (F) 24LBS (B) 28lbs

Not that much of a diference in weight: Stock with wheels 18": (B) 50lbs & (F) 49lbs vs Ruff Racing R-278'S 19" WITH Toyo T1R's (B) 56LBS & (F)50LBS.

According to the 1 H.P. lost for every 6 lbs formula, it looks like I am only loosing 2 H.P.

 

 

Go with 18" I'll sell you my 19" Volk time attacks

 

Do you have any pics? If I'm not mistaking, I believe Time Attacks are black?

 

lol at another gigantic wheel thread

 

Thanks for your valuable input.
