What's the specs for tires and wheels for a flushed fitment?
 

It's time to buy new wheels and tires for my GK and I am going for this fitment. I want to stay at 15" if possible

What specs are these cars running?
Do I need a spacer on the rear to square up the look? cause I noticed that my rear tires are more on the inside.

The camber kit can wait but what camber specs are these?

Thanks!
