Hi guys I have a 2010 G37S sedan. I am thinking about buying Rohana RC7 in 20s. What im really looking for is a nice aggressive look and for my car not to look Narrow from behind like everyone keeps saying. I want to minimize camber kits, rolling fenders and everything like that. I want a nice concave rim setup that fits to the edge of the fender and whatever I need to do to minimize fender gap. I want agrressive but I dont want to worry about ride quality. Offsets and everything is confusing to me. Im spending a couple or few thousand dollars and want the setup to look perfect for the car and make it look classy and mean. Please help

well just for example on my sedan I have 19x9+22 with 245/40/19 and 19x10+30 with 275/35/19 and that's as aggressive I can go on stock camber and fenders I cant fit any wider tire.. you can also fit the same size on yours or lil higher offset. just make sure the wheels will clear your sport big brake calipers.

Looking tight Dawg!

GLaw, What do you want to drop on~springs or coilovers?
As far as offsets, depends on how wide the tires you're planning, how much camber, etc.
Dawgs fit is tight, looks real good but may be a bit more aggressive than what you're wanting going by your post, hard to say though
Don't have a list of the available offsets for the RC7s, here's a similar wheel from Niche w/ available offsets.
http://www.nicheroadwheels.com/cms_p...1%20Verona.pdf

For a daily driver running as wide a tire as you can with in-spec camber I'd go~
20x9 (5x4.5 bolt pattern) +35 offset running 245/35/20 front
20x10 +40 running 285/30/20 rear

And like Kdawg mentioned, be sure to verify clearance for the big front calipers before ordering the wheels.

thanks blnewt

Kdawg your wheel well gap is perfect and you are as low as I want to be. And your wheels are lined up perfect to the edge of the fender like I would want. I was thinking just the Eibach springs for 1 inch i guess, I dont want to have to worry about camber kits and stuff but I dont want to be eating tires or rubbing. Its my daily driver and I want it to look right because its an expensive sport car. The Rohana RC7 I want can be tailered how I need them but the two regular options I can just order are front 20X9 with 32mm or 20X9 42mm and back 20X10 45mm or 20X9 42mm. I need help I appreciate it guys

thanks man and im on eibach springs too which drop it about 1.5 inches. the 20x9+32 and 20x10 +45 should be a good fit you could fit a nice wide 295 tire in the back too. make sure you contact the shop and ask them if the front wheels will clear BBK

Kdawg you are on 19 with the eibach drop and its perfect. If I got the 20s it prob would not work I would imagine right? and which eibach kit and do you have camber kit and if not camber issues?? and again I really appreciated the info this is my first expensive car and since I bought it there all around and I want a nice aggressive tasteful rim setup.

i got 19's and i dont see a problem with running 20's. i just have the eibach prokit for rwd sedan. and i dont have a camber kit no issues whatsoever

As long as you keep the same wheel offsets & tire treadwidth and go down a series in sidewall you'll be OK.

So I read 66 pages and what blows my mind is that nobody has made a chart/list of what works for the coupe and the sedan.

I recently purchased some Rays gram Lights that are 19x9.5 +25 and 19x10.5 +20.
Unfortunately, I had a Sedan Sport and there is no way I am fitting these without a lot of negative camber, stretched tires, and fender rolling.

I need to sell these to someone with a coupe and order a new set with different offsets.

I love the concave look, so I still feel like pushing the envelope of the offset.

As discussed the min. requirements for this thread should be 255 (F) and 285 (R).
I want to run 255/35 in the front and either a 285/30 or 295/30 in the rear.
I am performance influenced so I need a light weight wheel. With that in mind I am running the KW V3 coilovers and I'm pretty low.
(Currently on OEM 18's Sedan Sport wheels with 225/50 in the front and 275/40 in the rear.)

Ideal situation is no pulling in the rear. I don't mind rolling the front fenders though.
Camber should be close to the max negative specs. (I believe -1.75)
If I have to run as much as a -2.1 that's fine. I drive about 20,000 miles a year and want my tires to make it for 12 months.
So the real question is, what is the further you can push a sedan?
255/35 and 285 or 295/30?

From what I gathered, @MiPwnYew seems to have the closest I can tell visually.
20x9 +30 (that's +35 and 5mm spacers) 245/35/20
20x10.5 +45 running 285/30/20

Now going with the 19" wheel there would be a little clearance.

If I order another set of gram Light 57FXX 19" wheels:
What would be the absolute lowest offset and width I could go on the fronts with only fender rolling?
What would be the absolute lowers offset and width I could go on the rears with zero modification? (no spacers, no trimming/relocating of brackets or bolts)

Keep in mind Sedan Sport with Akebono's.
And someone please buy these other 57FXX off of me if you have a coupe. lol

So the vendor won't let you return the wheels? Too bad you didn't ask these questions prior to your purchase, but it is what it is

With in spec camber and perfect rear fender fit you can run my set in back which is 10" +45 running 295s. or a 10.5" +45 running 285s, w/ a 19" rim size you'd want 285/35/19s not the 285/30/19s unles you're OK w/ the speedometer error.

In the front I run a conservative 8.5 +40 on 245s but there's a lot of room up front since I don't want to hit anything on my stock front fender (that isn't rolled like the back).
If you roll the front fender you can run 8.5 +25 on a 245/40/19, if you want to run w/out rolling a +30 will work well.
a 9" would be a +30, and a 9.5" a +35 on a rolled fender and +35 and +40 respectively for the non-rolled.
If you run excess camber (in the -2.2 or more) you can move those offsets in a couple more mm.
Be sure to set up a FS ad in our classifieds, those are nice wheels so you should be able to sell them pretty quick if there's no way to exchange them.

Hey all, need some help with offsets and tires. Not a fan of stretched tires.

Can i run 19x9.5 +40 on front with 245/40 tires - lowered on Swifts and Koni's to come. will it be too close to brakes and do I need to a run a spacer to bring it more flush with the fenders?

I also will be running 19x9.5 +40 in the rear as well with 275/35.

Coupe or Sedan? Should be OK as far as proximity to the fender, might need a small spacer if you have a coupe but should be pretty flush on a Sedan.
As far as clearance for your big front calipers, that depends on the wheel design.
Here's a template for verification~

Thanks for the quickest response ever!

Non-sport sedan. I'm looking at avant garde M550's 5-spoke, or the M510's split 5-spoke.

The other dilemma is whether to slap on the dolphin grey finish or the silver finish as I have a graphite shadow sedan. Don't want too much of a blended look. But overall theme is that I still have a chrome window trim and in process of painting headlight housings satin black.
