I have the Shine widebody front fenders, was originally going with 18x9.5 + 29, but I can't find them anywhere.
Without getting flamed for asking, would anyone with Shine Front fenders happen to know the offset for flush 18x10", and if they will rub? Looking to use a decent tire , not stretched, for comfort. I was thinking +35 but for the cost, I want to be sure.
TIA

I run 18x11 +45 on stock rolled fenders with slight pull up front.

That is 7.77" back space which is max. 7.5" backspace is tje safe tried and true.

18x10 +50 is the classic stock body track fitment.

What do you do with the car? IE, how much camber do yiu want?

 

I have the Shine Widebody front fenders though. The stock calculator doesn't work for fitment. Spirited mountain driving and cruising mainly. Not much racing, maybe a 1/8 mile track here an there. No 1/4 miles in San Diego

So probably around 1 degree of negative camber up front (stock 0 deg).

With the +20mm fender I think you are right that you will want +30 offset wheel.

Wheel width doesnt matter, the offse is what centers the tire between fender lip on the outside and suspension on the inside.

You could run 18x9.5, 18x10, 18x10.5, 18x11, 18x11.5 or 18x12 with that +30 offset depending on tire width you want and how much stretch.
