Hey G37 fam,

Abbreviated Post (in case you don’t want to read too much):
I have a bagged 2013 G37x coupe and want to run Rohana RFX7’s in 20x10 with 245/30/R20’s all around. The wheel comes in +40 and +25 offsets, which setup will allow me to run minimal negative camber (close to 0 degrees) for ideal fitment with the wheel lips in line with the fenders?

Detailed Post:
I’m a long time lurker (almost 2 years now), first time poster, and I’m hoping you guys can help me out. Now I’ve been searching far and wide, and I have a pretty solid understanding of wheel specs, offsets, tire stretch, and all the things we normally spend hours calculating and recalculating for that perfect fitment (this forum has been HUGE in helping me understand what would otherwise give me nightmares about math class so THANK YOU).

I currently own a 2013 G37x Coupe on Air Suspension (Airlift Performance 3H kit) with rear camber arms and fronts on the way. I’m more so looking for solid rolling fitment; essentially the same fitment most of you have with your coupes lowered on coils at a drivable (not slammed) height, with the wheel lips in line with the fenders; and hopefully with that fitment it will still tuck when I air out. I’ve decided on the Rohana RFX7’s in 20x10’s all around, with 245/30/R20 Continental ExtremeContacts. They offer the wheel in both a +25 and +40 offset, and this is where my dilemma begins. I’ve seen some setups in this thread running 20x10 +25 (some more aggressive) and I’ve seen others running 20x10 +40 with similar fitment.

I’d like to run as little negative camber as possible. I moved to Florida and the roads are much better than where I’m from (NYC) so my ride height is pretty low but still easily drivable. I’m aware that the lower my ride height is the more the wheels will “naturally” camber inwards, which is why I currently have camber arms to keep the camber as close to 0 degrees as possible. So, would I be able to run the 20x10 +25 without running negative camber to fit? Or would I be better off running the 20x10 +40 and adding some spacers to get solid fitment?

I don’t mind having to trim the fender liner or roll the fenders, I think I’m on the same boat as a lot of members here and I’ve dumped more time and money into this project than I’d like to admit (and I got a LOT more to dump lol), so some more time on my fenders isn’t a big deal.

Thanks in advance for your help, there’s some really clean G’s in this thread and I hope to add mine to the lineup when this is all figured out.

Good Morning All,

I have a question about fitment for my car. I have a 2012 g37x sedan and I'm looking to buy some wheels and tires. I have swift springs coming in in approximately a week or two so would like to order something soon.

I'm looking to run the setup seen in this thread below:

https://www.myg37.com/forums/private...-esr-sr08.html

ESR SR08 ----- 19x9.5 +35 all around with 245/40/19 tires

Would this be an easy setup to run with no need for any additional parts (spacers, camber kits, toe kits, etc) Just looking to slap these on with some swift springs and be happy for summer with no issues.

Thanks for your input.

Simpsons coupe running 20x10.5 +25 on 275s here~

So running 245s would give you an extra 15mm on the inside & outside, and running a 10 instead of a 10.5 will gain another 6mm clearance.

You'll be similar to my setup 18x9.5 +38 running 245s all around.
Wheels will be a bit outside the wells but will tuck fine but you WILL need at least a rear camber kit, especially the toe kit to keep rear toe in spec, this is critical for good tread wear.

Thanks for the advice. Is there any rear camber kit or toe kit you recommend? Are they two separate products? Thanks for your help.

SPC rear camber arms typically include the toe bolt kit, just need to confirm that w/ vendor, and this will require cutting the current toe bolt slot to allow a wider adjustment range for the new toe bolts.

Looking for a little guidance for running a square setup. I was wondering if there will be any rubbing or clearance issues for a 19 x 9.5 +35 wheel setup with 265/35/19 tires all the way around? 2011 G37 Sport Sedan, stock suspension

zaz

I have 19x8.5 +35 w/ 265/40/19 all around, no issues, stock suspension, 2011 G37xS, if that helps.

Since you have an S you'll need to confirm brake clearance w/ whatever wheel you decide, and zaz comment is based on a 8.5" width, your 9.5 will be 13mm further out from his. I run 18x9.5 +38 on 245s all around, I ran 285s in back on the same wheels and they tucked ok. Have room for 255s in front but 265s you may have to flat roll the front fender edge. You will have poke at stock height too.

OEM coupe 19x9 ET45 anniversary edition wheels, 265/35/19 RE-11 all four corners. Plan to switch back to the stock staggered 18's with Conti DWS for winter.

Would've loved to lower no more than 1/2 in, only Impul springs will fit my need, but needed special order and probably a long wait. Will stay stock height unless I get lucky.





Been wanting the 19' version of these wheels, missed out on the fire sale few years back, been punching myself ever since. Used sets are hard to come by. Finally sucked it up and bought a brand new set via ebay.

Look good, might consider some Z springs, IIRC there's a small drop w/ them.

cv129

I think it's small drop in front, but too short for the rear. I do have a set of OEM Nismo Z springs and shocks just sitting in my garage though.

If you've got the time might be a worthwhile afternoon project. If you do this post back w/ your results, would be good info to share.
