So I decided this past weekend to try and utilize some leftover 15mm Ichiba version 2 spacers. my Normal offset is a et 25 on a 20x10. this would make it a 20x10 et 10. I began with the driver's side and slowly aired the car down. it just clears most of the inner fender lip of the seibon fenders. Only slightly pushing the fender out a bit, near the front area where the fender, meets the front bumper.
Should be easily fixed with a dremel and some rotary blades.
Last night I trimmed the inner lip on the driver's fender. It was successful. I was ballsy and did this without removing the wheel (since my buddy had my torque wrench). Tonight I am going to remove the wheel and torque the spacer down within specs. I'll attack the fender a bit more to ensure there is no possibility of it catching on any portion of the fender. Then, I'll hit the passenger side and call it a day.
HIN is having Hot Import Days Seattle this weekend. So, a good majority of the week will be spent on final car prep for the show
