I have a 2012 G37 sport coupe. I will never do any suspension upgrades; no lowering springs, no coilovers etc. My question is, what offset do I need the rims to be in order to have them flush with the fender. I plan on getting 19x10.5 or 19x11 (19x11 if they will fit) for the rears and probably 19x9 or 9.5 for the fronts. I do not want to have to trim any brackets or anything and of course I do not want to rub, I do not want to alter my car at all except for the rims and tires. Can I even achieve rims this wide with an oem suspension and no alterations to my car at all?

 

A 9.5 +30 F running 255/40s and a 10.5 +40 running 275/35s will work, anything more aggressive will poke a bit outside the fenders at stock height.
If they have a 11 +45 that would work as well.
I'd still consider at least a mild drop though, but

 

Thanks for the info blnewt!! Never could really find the answer I was looking for. You are the man. Go Broncos.

 

I hope your fitment comes out like ****. Go Panthers! Lmao

 

Careful G, you're only one small click from getting banned

 

blnewt, you suggested that I run 275/35's in the rear as opposed to the oem 245/40's. What is the reasoning for that change? I understand that I will need to go from 245's to 275's because of the wider wheel but why the change from 40's to 35's? Will I rub if I do 275/40's? I feel like if I run 35's I'll have a more defined fender gap, which no one wants.

 

275/35 will even out to about the same overall diameter as a 245/40. A 275/40 tire is taller than a 275/35.

 

Yep^^^ As you go wider you need to go down in sidewall series to keep a similar diameter. The sidewall series is a percentage of the width, so a 35 series means it's sidewall height is roughly 35% of the tires' width. Hope that makes sense.

 

Lmao YOU AINT REAL just kidding. May the best team win hahaha

 

Will this fit my 2wd g37 journey coupe lowered on Eibach springs?

Front Size:

20X8.5

Rear Size:

20X9.5

Offset:

Front & Rear: 35mm

Bolt Pattern:

5x114.3


Hub Bore:

73.1mm

I just ordered Eibach Springs and wanted to do the wheels when I lower it. If it will fit, roughly what would the offset look like? Better than stock? Also what size tire should I go with? I've been driving myself crazy the last few days looking through posts. Sorry if this has been asked before but I desperately need help!! lol

 

Do you have a link to the wheels you're wanting? Those will fit OK but you may want a bit less positive offset to be more flush at the fender, and for a staggered setup you may want a bit wider wheel in back if available

If you're set on those wheels I'd run a 245/35/20 front and a 275/30/20 rear tire set

 

Thanks for the quick response!! Roughly how far would they poke out from the fender? Here's the link 20" Grey Machine CV1 Concave Style Rims Fits Lexus IS250 is350 GS G35 G37 M35 | eBay
Could I go with a small spacer in the rear to give them a more aggressive stance or would they stick out too far in the front?

 

You'll be OK, and if you want a more flush fit wait until you get them installed and see how much spacing you want. Use this calculator when trying new combos and use these figures for your stock coupe wheels (if that's what you still have)

Front & Rear 18x8 +43mm offset

FWIW your new wheels would be 14mm further out in front and 27mm further out in back, so you're going in the right direction. With the 245/35 front tires and 275/30 rear tires you may like it just fine as is. Simple to add spacers later on and much better than ordering too much or too little spacing ahead of time (and you might not want any at all)

Thank you so much for the help!!

 

So when summer comes along I'm debating on letting my old man use my Vossen's for the season on his 2015 Nismo Z.

I was wondering if the stock Nismo wheels would fit on my X Sedan? It is lowered on Swifts. The front I imagine will be fine, I'm just concerned with the rear offset.

Wheels:
19" Forged Rays
Bridgestone Potenza S001

F: 19x9.5 +40 : 245/40
R: 19x10.5 +23 : 285/35
