front wheel backspace
 

im trying to figure out my front wheel backspacing,so I can order wheels. I have a scott mock subframe. running 18x10 inch wheels. if I go with a 7inch backspacing, It will be one inch inside the front fender. is this enough clearance? I don't want to have to buy a 400 dollar tool to figure out my backspacing, any help would be appreciated. thanks guys!

That should be fine. We ran a similar frame and used a 6 7/8" BS on a 10"
