Good question and not sure how much I can get with plates anyway. I looked at the tires again. The inside edge just has a slight amount of tread left on the fronts and the rest is a slick with a corded edge on one of the fronts so I'm not really that far off. Negative 2 degrees would probably be about right. That's what I had on the GT500 and it wore evenly. I actually corded the inside of my R6s on that car. The rears actually have more tread on the inside edge than the front so on the next set I might flip them on the rim after a couple track days to extend the life since we can't get any camber back there.Dean#4AI said:How much more camber do you think you will need? Hate to go much more than 2 degrees and still drive it on the street.

The 285s require a 9.5-11.0" rim per Nittos specs so that 18 x 9 rim is too narrow to work effectively. You could probably mount the tire but I don't think it's that effective (or necessarily safe) to run tires on rims smaller than the mfr suggests. The tire will just bulge and your actual contact patch gets reduced so you lose the benefit. The tire sidewall also won't be as stable. That said you could probably do it, but I personally wouldn't. To find out just mount the 255 tire on your car and check the clearance from the sidewall to the strut at its closest point. The width difference between the two tires is (555RII=11.22") - (555=10.16") = 1.06" so you will be .53" closer to the strut with that 285/35/18 tire. I know some people will go as low as 1/4" or less with a stiff sidewall tire, but I'm more comfortable at 3/8"-1/2" clearance.2012Boss said:Gary
Since the 555 II's on come in 3 sizes can the 18's be used without clearance issues? I mean did you do anything special to the car so they did not rub or can anyone just bolt them on, I know you have made some changes. Would they work for example on these 18x10/18x9 rims?
They are 1" wider both front and back than the stockers which is what makes them so nice ;D The only changes I made was to add .75 degrees of negative camber. I don't think the fronts would rub the fenders with the stock level of -0.95 degrees of camber but since I never put them on the car without the additional camber I can't say with 100% certainty, but I really doubt they would rub.2012Boss said:cloud9 said:I just went ahead and ordered another set of 555RIIs for now.

Don't know if you saw my question about the 555 II's. Do they fit just fine or do you special offset rims and other changes? They are pretty wide compared to the stock tires, correct.
