Not a good angle, but running downforce front fenders with ccw 18x10.5 with 70/50 offset rear/front. 285/30/18 advan neova ad08. haven't had it corner balanced and aligned with the new setup so ride heights are a little off, as well as camber. Fronts rub at the last 5 or so % of full lock. I have more pictures, but am not able to find them atm. I'll post when I get more

How much space would you say you have between tires and fenders front and rear? Looks like you went a little more conservative on width and offset than I was thinking, but if you think it's maxed out, then I might be too ambitious with 11's. 10.5 is still a good width for 285s.

Do you have BBK clearance up front?

Yeah that set up is conservative.

There is still another 10-12mm outer and inner fitment to play with all the way around. If you want to get specific for best fitment on 11's, you want 11 +63 rear, and 11" +42 front with +30mm DF fenders. 285's

See this thread - on stock fenders.

You should be able to get more under there with DF fenders.

s2000 junky is pretty spot on, about 10ish mm more. This is good for me as I plan to run 8-10mm spacers since I plan to run the 6/4 stoptech kit and don't think they'd clear currently. Running their st-40 328x28 kit up front and they barely clear with no spacer. and for clarification on initial post, since I didn't specify, I meant rubbing on front on inner control arm.

Hmm so feasibly 18x10.5 +47 and 285s could fit with just Downforce fenders? I always thought it would be way too wide...

Please enlighten me as to how you calculated this. I'm sick of scrolling through thread after thread and I know there must be a calculator somewhere...

Well ive got a lot of experience with fitment on my own car and so that certainly doesn't hurt to draw from. But you need a basis fitment to start from that you are familiar with, which may be stock wheels. From there you can measure the available room in the fender wells to match the width wheel you are looking to go with, wile also factoring in a offset. The width as well as offset placement of that width will determine your inner vs outer clearance. If your basis to start from is a stock 8.5" +65 oem wheel, and are not sure how to divide and calculate offset and width in your head to come out with the new wheel spec, you can use the website willtheyfit.com and put in the old vs new spec wheels and let them calculate for you. But its only a calculator, its not going to tell you if they will fit or not, which is where the experience comes in I guess. If you are running a wider fender over stock, then you just incorporate that added width into the new wheel spec if you want to maximize them.

I just fitted a new tire set up this winter btw, 275/4017-315/35/17 stagger. Still "stock" fenders. Same 10"/11.5" wheels I ran the old 255/295's on. There wasn't much wiggle room left at all on my fenders, but with a little pulling, messaging, trimming and slight suspension height adjustment to compensate for the slightly taller tire diameter, I was able to pack them in. The additional widths were not much, as the XS ran wide for their sizes and the NT05 run narrow. So I pretty much split the difference on the up size which made this feasible feat to try.
