Have driven my car with this set up 31,000 miles in LA traffic, with absolutely no rubbing issues. Furthermore, have turned 12.60's at LACR with this set up. From the start, I said they will fit, AND I KNOW BECAUSE I ACTUALLY RUN THEM ON MY CAR---FIRST HAND EXPERIENCE. They do not rub. If they haven't rubbed in 31,000 miles, then they are not going to. And they DO NOT stick out with a 255/45/18. And lastly, you do not want to lower your car to screw up weight transfer at the track, unless you are prepared to do alot more than just
lowering springs. Thats why I haven't lowered mine. I know what I am talking about, I 60' regularly in the 1.6's. What do you 60'? Oh, but your car may look better, so we have different priorities, and thats where are opinion differs. And as far as safety, I couldn't agree more, however. No one would argue you on that. If my
tires ever rubbed, then I certainly wouldn't be running these
wheels, especially when I am going close to 110mph in the 1/4 mile. Below is a pic of me running this set up at the track before my DR's. If they rub like you say, how do you explain the picture below?????All of those passes at the track, and no rubbing.
Like I said before, if you want to get the largest tire possible under the car, then yes, you need more then 24mm of offset on a 9 inch wide
rim, we are also in agreement there. When I run my DR's, since they are a wider and taller tire, I run a 9 inch
rim with +42mm offset.
