I personally wouldn't go with 25 in the front if you are going 20 in the rears. Either do 25 all around or 20/20... I rolled my fenders which is very easy to do/get done and I have a good amount more room to drop now, and that is with my 255/40 tires, I was nowhere near having problems with oem size

I never said I was going to go 25 front/20 rear... Anyway I went with 25 rear/20 front and I think it came out perfect for the oem's. any wider in the rear would have forced me to go neg camber to get the drop i want. Haven't dropped it yet, still need to get the fenders rolled, but I'm looking at being able to go at least 1" in front and 1.5" in rear. Also im thinking of going 255/40/19 in rear instead of 265/35/19, I think it will fill out the fender gap a bit better. BTW Ichiba V2's...

^ Yup.

I'm pretty low with 25mm rear/20mm front with stock sized (245/40/19 rear, 225/40/19 front) tires... ordinarily, they don't rub, but if I go up a driveway at a certain angle with the wheel turned too much, they will rub. Also going over certain imperfections in the road will cause some rubbing.

update. Ichiba V2 20mm front, 25mm rear, with OEM 19's 245/35/19 front, 255/35/19 rear. Dropped on JIC Magic FLT Coilovers almost all the way. Damper settings 10 front, 8 rear. SPL front arms/rear camber arms. Have about 1/2" wheel gap on all 4 wheels, no rubbing, no rolled fenders. This is absolutely as low as you could go without any clearance issues or rolling the fenders. Off to Roger Krauss for minor adjustments and corner balance next week.

Ahh well I guess you read right to left and say rear to front as opposed to the norm. Looks pretty good with your drop although I think 25mm in the front would give it that bit of increase to get the nice flush look. Drop looks pretty good, too bad you can't go a bit lower to get rid of that last bit of gap.

yeah, i noticed that I was a bit *** backwards with the front to rear thing. Pics were 2 days ago right after the coilovers were installed, it has settled nicely and i only have about 1 finger gap all around now. After playing around with the rear coilovers I realize I could have probably gone lower but I'm gonna wait and have a pro do the fine adjusting.

How safe is it to run 265's on oem Rays? I do drive aggressively and would hate to have the tires slip off.

I know from a liability standpoint, most manufactuers don't recommend it on 8.5 wheels. I have yet to find an example of the tires actually slipping off, but don't take my word for it. If you are going bigger your concerns would be more about sidewall flex, decreased contact patch and affecting your abs/vdc. There's a great thread here that discusses all the different tires people are running on their oem 19's, some are even running 275's and say they haven't had any problems https://g35driver.com/forums/wheels-...ll-thread.html.

Anyone know the torque spec on the spacer? Is it 80lbs? Same as our OEM wheels?

How low is your car? I pretty much have the same setup as you except different coil-over brand. I have about 10mm on the front wheels and 25mm on the rear wheels.

I'm about 1 finger gap all around now since they settled. It's slightly higher on the right rear but just needs a bit of fine tuning. I'd say about 8-10mm all around.

Your car look good. Anyway you can take closer pics? can you take one showing the side view? I want to see if your tires stick out or not on the rear and front. THANKS.

They don't stick out at all. I'll try and dig up a couple of pics.
