Maybe it's just how the sidewall is on the R888s, but I was convinced that no roll should be required for a 17x9 +54 using a 255/40 tire

 

My guess is that it's because he is so low. I run a 255 +62 in back and am ok without a roll (barely). But push that 8mm farther outward and slam the car like that and a roll is probably necessary.

 

Dang...I'm definitely going to be looking at +60 or higher from now on. :/

 

It could also just be a camber issue. Before rolling the fender lip try running more negative camber. Run the most negative that Honda recommends and it could work. The problem is that tires are all different shapes even in the same size.

 

It could be any number of things mentioned, height, camber, tires, etc. They all factor in. I rubbed in the back with a 245 17x9+60mm with an inch drop. Even running a high offset like a +60 or +63 rolling is recommended especially with a 255 tire. It's not an exact science since no two setups are alike.

 

It's how low he is. I run 17x9 +63 all around, with -2 camber up front, -2.8 in the rear, 255/40 all around. The rear clears easily. The fronts I rub on the fender liner on big dips. I have a 1 finger gap all around.

 

^^^You think you could get away with -2.0 in the rear?

 

Yeah, probably. But, it'll depend on what tires you run. I'm running Hankook v12 ventus, I'm not sure how they compare width wise with other tires of same size.

 

you will be fine with -2 in the rear and lowered 1 inch. Run the UK alignment, imo

 

Do not run the UK alignment rear toe, unless you like twitchy handling, poorer turn-in response, and literally twice the wear rate of a more reasonable spec.

I would go with a MAXIMUM of *HALF* the 0.64 degree total rear toe that the "UK alignment" calls for. Preferably 0.2deg total.

-2degrees is no big deal for camber. Could go to -2.5 even and not have totally ridiculous wear (~10-15% reduction in tire life if you don't flip them).
