I plan on going with 18x9, 18x10.5
245/40/18
275/40/18

Or perhaps 275/45/18

Post the full specs of your setup for us? Look nice imho.

What offsets, +15?

18x9.5 +35 all the way around. 30mm spacer in the rear.
Tires are 255/45 and 275/40

245/40 is 4% smaller then OEM and 275/45 is 4% LARGER then OEM. Your ABS will go insane due to the front and rear tires rotating at a large difference of rotations per minute. If you want a 245/40 up front then run a 275/35 in the rear. If you want a 275/40 in the rear, run a 255/45 up front so atleast they match or atleast much closer to matching. You also have the option of 255/40 or 245/45 for the front with a 275/40 rear.

I know this is a little off topic but what's the widest tires I can go with on the base wheel ? The reason I ask is because I plan on installing H&R spacers 15 up front and 20 in the rear.

Stock widths are 225F and 245R. I wouldnt go more than 3 sizes bigger than the stock width. So maybe 255F and 275R. You can probably do more but its pushing it. I would be safe and to 245F and 265R.

Thanks mike I'm due for tires soon so was considering wider tires.

Question... I found a decent price on a square setup the only thing I'm worried about is the offset. The wheels are 18x9.5+35. I do have spacers but just don't if it will big enough to push em out.

I have the same offsets I ran a 30mm spacer in the back and nothing in the front. Looks pretty good to me

Cool if I do end up getting these. I got a 20mm spacer so I'll try that and see how I like it.

Well just checked them their varrestoen 18x9.5+22 all the way around with nitto tires. With that offset in the rear should I be ok with a 20mm spacer.

You would be similiar to my setup. The rear would be a +2 which should look nice, doit!

By any chance you got a pic of the setup?

Here's my contribution

latest pic (still with no spacers, have yet to find the time):

Looks good Micheal... I just put 20mm H&R with extended studs on today here's what it looks like.

wow man :tup:

18x9.5+25 and 18x10.5+15, tires are 285/35/18 Hankook rs3 square. I just bought enkei nt03, 18x10.5+30 square setup, will run 15-20mm spacer in the rear.

18X8 5-114.3 20BCM
18X8 5-114.3 40BCM
18X9 5-114.3 35BCM

These are the sizes I have to work with, anyone have any suggestions? I don't track and would like to stay staggered, but I'm not sure that's possible. I have a Base and don't mind working with spacers, but I wont drop because of the atrocious roads around here...

I assume the "BCM" is offsets? If so and you wanna stay staggered, 18X8.5 +20 with a 10mm spacer. 18X9.5 +35 rear with a 35mm spacer. Not really good choices for the Z....

What if I went square with these 2
18X8 5-114.3 20BCM rear
18X8 5-114.3 40BCM front
would that be better?

That would put your rear at skinnier wheels then the OEM wheels. Also you would need a 20mm spacer on the front and 35mm on the rear and it would still be sunk on the rear.....Reason for going with these terrible wheel sizes and offsets? No other choice? OEM base wheels are 18X8 +43 front. 18x9 +15 rears. I think you need to do a little more research on wheel sizes and offsets for our vehicles. If you want square, 9.5" wide is what would be recommended. Staggered is usually 9.5" fronts, 10.5" rears.

Nailed it. They were a set of Konig deceptions. the local discounttire had some in stock and were trying to move them. Those were the only sizes they had and they look good. I have seen some on a Z before, a user here has them and they don't look that bad.

EDIT: found it

I just checked and 18X9 is actually the size. Not 18X9.5 but do 18X9 +35 all around if you are set on those wheels. 10mm spacer on the front. 35mm spacer on the rear. A 15mm spacer would be more flush but your rears wont be as flush so it'll look weird. Use the same tire size all around so you can rotate. I think it's the only good option. I would run a 275/40/18 all around but a 245/45/18 will keep your stock size if you don't want wider.

yea they want 900 for the set, so I am really tempted. I guess Ill just hold out for now.

I think those are avant garde m368 19" not 18" he has

I wouldnt buy those, that is hella sunk status and Konig is a cheap brand. There are a lot of better options out there. I bought my Enkeis used with almost new Falken FK542's for that price. A brand new set of Enkeis 18x10's would come out to about $1100 if you went to Top Speed in Dallas.

Is there a set up that would look good with 18s at stock height while filling the wheel gap?

This is how she sits after spacers and newly installed spoiler , now I'm just waiting on my rear tires to come in.

I dont think you are going to fill the gap with 18's. On mine, my tires are actually smaller in diameter than stock since Im running a 275/35 so Im scraping a bit more being on springs already. I didnt want the thickness or the price range of a 275/40. That seems to bump up the price a lot even in 265's but its necessary if you want to keep the stock diameter. If you want to get rid of gap you have to drop it but on 18's you will be scraping and fearing speed bumps. If you dont want to be that low and just want to get rid of gap, go up to 20's and drop it.

Looks good but a drop will make it look even better

Would dropping the car on springs get rid of the gap if I am running 18s?
Coilovers are a little out of my price range while I am in school.

Thanks yeah I plan on dropping it but, I'm waiting to see how a 285/40 will look once they come in. Since right now I'm running a 30 profile tire the gap is a little noticeable.

Im on Tanabe springs, drops an inch.

You have plenty of options with springs to go with a mild drop to an aggressive drop. Swift springs are gonna be your biggest drop. Eibach and tanabe are gonna be more of a medium drop and Nismo springs will be a mild drop. Heres of my car yesterday driving. I'm on Tanabe springs with a 275/40 in the rear and a 255/45 on front. Same diameters as OEM.

I'm set up the same as ^^Chris but with the eibach back. Swifts have been the fan favorite on this forum, i like them too. Eibachs are good for me tho bc the roads here in tx aren't great.

here are the new nt03 I ordered, time to get tires mounted. 18x10.5+30 enkei nt03 square, will need a 15-20mm spacer in rear

Martin82, what are the weights of those wheels?

21 lbs per enkei website, they aren't forged but very strong got these for track!
