So I decided to get back into the game and do something with my g37.
megan racing coils LP street series with camber plates on its way
OEM front chin lip on its way
Billet front license plate re-locator on its way...
my question is which tire package makes more sense for my car without any issues..

1. 235/35 R20X9.5 with 30 offset fronts
275/3o R20X10.5 with 35 offset rears (little stretch) tire diameter on this set up is 0.07

2. 245/35 R20X9.5 w/ 30 offset fronts
285/30 R20X19.5 w/35 offset rears.

I don't want any rubbing nor i want to cut anything or roll fenders..
any input will be appreciated.

 

Coupe or sedan?
The Megan coilovers don't come w/ camber plates, that's just a feature of their overall line, you'll still need aftermarket camber arms.

Which tires/wheels are you wanting? The tire sizes are fine for staggered sets but running staggered tires on the same 9.5" rims is not a good idea.
Maybe you just had a typo for option 2 ??

Thanks... option 2 was a typo... rear rims are 10.5 and it is a sedan. AWD
The website for megan racing states the LP street series come with camber plates... I will call to make sure...

 

[QUOTE=jnova;3790128]The Megan LPs don't have the camber plates, how do I know? 'cuz I have them

As far as a stagger setup on an X sedan, your offsets are a bit too aggressive unless you want to run heavy camber (which I wouldn't recommend for a daily driver.) Your tire sizes are OK, the 245/35 and 285/30 will give you proper diameter. For 10.5" rear you need to be in the +45 offset area. My 10" +45 running 295s is flush FWIW. The front fender isn't flat-rolled from the factory like the rears are so I would have offsets in the +40 range. If you roll the front fender you could run +35.

 

[QUOTE=blnewt;3790228]I had the shop check diameters and both tire set ups are under the 3% rule.
Here are the exact specs...
235/35 20X9 fronts 30 offset
275/30 20X10.5 rears with 35 offset. - 0.07 diameter

The second set up
245/35 20X9 fronts 30 offset
285/30 20X10.5 rears 35 offset. +0.07 diameter
This is my daily driver and don't want issues so please give me your best recommendation as the wheels are going to be concave as well.
How do you like the Megan coil overs?? Specially if I want to ride close to stock.

 

[QUOTE=jnova;3790431]Like I said, the tire sizes are fine, both combos are well under 1% variance, the AWDs should be under 1%, RWDs is OK closer to 3%.
The offsets need to be a bit more positive, your wheels/tires will be poking out from the fenders about 8-10mm depending how low you drop your coils.
The offsets in the +45 rear and +40 front would be much better.

As far as the ride on the Megans, I've got mine about a 3rd up the firmness scale, about 13 clicks up from full soft and found this a good point for daily driving.

The ride w/ 20s and coils will be MUCH firmer than what you're used to if you have 17 or 18s on stock springs though.

Thank you for all the input...

 

It'll look great with that fitment. The car sits great with that 20x9/10.5 setup. I've used a +37/+42 offset and its money on the G37.

{STR 607 20X9 235-35 Nittos, 20X10.5 - 275-30 Nittos - Megan Racing coilovers- GMG Motorsports NO HOLES license plate relocator - OEM sport front lip - Duraflex GT spec roof spoiler} more to come.....

 

Must say you've put it all together very well, love that wheel color w/ your cars' paint. The drop and stance looks just about perfect, did you get it aligned yet? Where did you set your coils, I have mine about a third up the firmness scale.

 

Thank you...
All aligned... I'm in 13 from soft for comfort ride... Front responds well rear is a bit stiff...
