My car is the same chassis, but slightly different fenders. I have 18x9 with 255/40-18 on the front of my car now. Pretty sure 275/35-18 will fit easily. I currently have 18x10 with 295/40-18 in the back, but I have a LOT of clearance. I previously had 325/50-15 drag radials tucked under the back. I had to modify the front fender to clear a 26" tire on turn in. But, definitely a different fender on your car, so hard for me to say.
