I would have kept the 285 tire since you where going to lower. the negative camber would have taken care of this slight rub you had.
for the front you shouldnt need anything more then 5mm to clear the OEM calipers. Bolt on will require 15mm or more and may look funny with the rear.
I say go back to the 285 tire and drop the car 1" or more and it will look good and work.

Do you really think if i lower it 1" the rears will fit a 285? It looked SICK with those tires!!! Really beefy.
I would hate to put on that tire just to have it rub when I take the car out for some spirited driving, possibly damaging the car or tire, or both. Also, wont the negative camber cause the inside of the tires to wear much faster?
I used to have a Supra and had to use washers to get the camber corrected so the tires didnt wear out on the inside.

1) You can get a 10mm Wheel adapter from Project KICS or the Ichiba TypeII. Both have built-in studs and uses smaller lugnuts to install the wheel adaptor to the OEM hub. The project KICS wheel adapter is not hub-centric (OEM hub to adaptor) since they do not make hub-centric adaptors until you hit 15mm or higher. I currently run 10mm fronts and 15mm rear on the OEM x-package rims for 2 years now, no problems as long as you properly tighten everything down.
As for using 15mm spacer for the fronts it would give you an 25 offset on a 8.5" wheel which would stick out too far. Remember the front wheels turn, so you should also put into consideration whether the tire would rub when you are turning and the suspension compresses. If the wheels are flushed with the fenders when going straight, it will definitely rub when you corner. Unless you add some negative camber to the point where the front wheels are tucked inside the fender to clear it while under load, you are probably going to need a narrower tire to clear the fender with a +25 8.5" wide rim. But too much negative camber will give you crap handling and result in uneven tread wear...
2) Your 275's look "crap" on a 10 inch wheel because that's a bit on the narrow side for a wheel this wide Usually 275's are shod on 9'5" wheel and the perfect size is for a 10" wheel is 285. Go look up the tire manufacture's specs under "measured wheel width" and it will tell you which wheel width they used to design the tire for.
Something tells me that the set of wheels you have wasn't customzied for your IS and tire application. There are guys on this site that had fitted 295/30R19's in the back on 10.5" wheels on lowered suspension and without fender mods, you just have to get the offset and disk face right.

As for swapping tires to a 285, thats easy to accomplish since my friend works for the tire store and will swap them without question.

Ordered H&R 10mm hubcentric spacers for the front. Hopefully that ixes the fronts. If not, the wheel store said they will order me another set of wheels no questions asked.
