I was currently at a 6/7 drop on 215/70r15 all around. I wanted to add some more tire in the rear, so I put on some 235/75r15, which turned my 1" rake to 2", so I dropped the rear another inch.
I'm currently at a 6/8 drop without a notch. So far so good. I ordered some 15x8 & 15x10 Series 42, but are on backorder for the next few months. I honestly can't bring myself to put on a wheel other than OE rallys or Cragars. I like it boring, I guess.
