They dont make a 235/40/19. You could run a 225/40/19 and it would still look pretty good. But the 235/35/19 should fill up the gap pretty well with the eibach drop.

Gdup - Do you know if there would be any front brake clearance issues with the 19x9 +29 given how concave they are?

hans127 - Something to consider about running a 235-35-19. That tire's diameter would be more than an inch shorter overall than the stock F: 225-50-18 and R: 245-45-18 that comes on an 07+ G35S. Therefore, you will have a bigger gap in your wheel well.

It can still look really good, but you would just need to lower your car more. Otherwise, it will make the rims/tires look kinda small given the greater wheel well gap. The other issue is, it will throw off your speedometer and odometer.

Here are the diameters of the stock tires and some tire sizes people run:
stock: 225-50-18 = 26.86"
stock: 245-45-18 = 26.68"

235-35-19 = 25.48" (note it is much shorter than stock)
245-40-19 = 26.71"
275-35-19 = 26.58"

Just something else to consider.

 

Dude, you need to take some pics of your car lowered on Impul springs and post them in this thread:

https://g35driver.com/forums/v36-brakes-suspension-wheels-tires/184925-impul-springs.html

People are dying to see what a G35 w/ an Impul drop looks like and they just keep getting teased by the flakey OP.

 

I wouldnt forsee a problem with brake clearance issues. The concave on them is pretty similar to the wheels i have and i've got enough room for a BBK.

He is also planning on going from an Impul drop to an Eibach drop, so it will take away the wheel gap.

Would the G37 245/40 rears work with the Advanz?

 

The 245/40 would be a little wide for the front. It could work on the rear though.

Seeing and driving my car every day and then putting the impuls on made me appreciate it a little bit more, even if it isnt a significant "drop" per say, beauty is in the eye of the beholder. yeah, ive been taking the gradual route in terms of lowering my car. Ive just been concerned with the camber situation when lowering more than an inch. What companies offer camber kits for our car anyways? know how much they are?

 

I dont think anyone currently offers a camber kit for the 07's.

so there prob would be some rubbing in the front?

 

I wouldnt be able to say for certain. I couldnt tell you 100% and that's why i recommended a skinnier tire.

What's the front tire size on the G37 wheels? 225/40/19 right?
-GP-

 

I know the 235/35/19 would be a little bumpy....225/40/19z would prob be a little less bumpy?

 

225/40/19 would ride just like the G37 wheels you have on now
