Roll the fender tabs in the front at least. You will rob the inner wheels on the upper control arm with 17x9 +60. and also the outer edge fender liner.
I heard this may happen, but it is only during full lock of turning right with steering? Anyone have experiment with 17x9 +60mm offset wheels like Enkei PF01 with a STR ride height (12.75-13.25") and front fender tab rolling. Do you get this same issue as well?
I've experimented with +63 17x9 with 255/40/17.

Just roll the tabs in front. If you're 12.75" or above with typical STR spring rates and camber you can do it without rolling them and some do and go a while without major problems but a) you'll tear up your fender liners much more and b) if you hit a bump with the wheels at opposite lock you will catch the tire on the tab and rip your fender into some crazy shape...and that's not reversible. It's just two tabs you have to bend up to prevent this, don't even have to use a fender roller. Even at 13" or 13.25" it's possible to hit the tab. Just bend the tabs up.

Once those are rolled, you can comfortably do 12.75". You'll likely rub the inside of the wheels at full lock (just don't drive at full lock) and your fender liners will wear little holes and be a wear item but it's not bad.

In the rear you can really slam it without having to roll anything if you want to, lowest I've run is 12.4" but you can definitely go significantly lower than that - wouldn't recommend it though.

Thanks for your info. Helps to get some experience from a STR competitor. I have already ordered the Enkei wheels just deciding on tire brand. I will plan on keeping the ride height at lowest of 12.75" based on your comments. For the rear height, I will most likely keep it slightly higher since under acceleration it would help level car for better balance. Unless anyone has comments about that.

Mine, stock, is at 14" front and rear. Are the tabs those push pins holding the inner fender on? My are mostly gone already.

I am leaning to the Enkei for two reasons. First, Tire Rack doesn't have the TRM C3 in silver, just grey and black. I really wanted silver. Second, I've received lots of feedback here that the PF01's hold up to potholes and rough roads. Bending wheels is a problem around where I live in north central NJ and even worse closer to or in NYC. Enkei is also an OEM wheel manufacturer.

I was probably going to drop the car .25" to bring it back to stock ride height, so that would be 13.75":. Not sure about the camber but mostly street driven the camber would probably be mild, -1° to -1.5°.

The 3mm difference in offset is about 1/10th of an inch.

How about stock height? Would it rub?

17x9 +58 is going to be a minimum to fit

17x8.5 +54 is the minimum for an 8.5

If you are going for the popular 17x9 +45 you are going to need a roll and pull

I don't believe camber being a tool to fit tires. Camber should be an independent available tuning option per track/condition; not a requirement

Also regarding camber are you pushing the track out via an offset lower ball joint (ie Megan, hard race, Js and spoon) or are you pulling the upper a arm in a la SBC? Leaning the tire in with the SBC will give you fenders more clearance and expense of possible rubbing on the control arm (again depending on wheel offset)
