Folks, my favorite online calculator for this is now only available for a fee (i.e. rims-n-tires) so i'm going with an educated guess on these sizes. Mind helping me with these?

My goal is to get everything to fit without rubbing and a mild drop comparable to Eibach's. Minimal camber as well (in the 1.6 - 1.9 range) and getting that rear to look nice and meaty. I am not a big fan of stretch tires.

F: 20x8.5 +20 or +25, 245/35's
R: 20x10.5 +40 or +45, 285/30's (If i can fit 305s, that would be nice. 275s are too stretched for me in this wheel width).

I've looked at various set-ups in the Media Share thread as well as made my own crude calculations based on the current set-up. I feel that this will fit just fine and be actually on the semi-conservative side. Not too tucked, not sticking out, just right.

Any thoughts on this?

Thank you.

p.s. I referred to this calculator for the offsets, the lower offsets should put me at +5mm further out all around compared to my current set-up, which would be perfect. But, i don't know how the wider rear tire (285 or 305) will affect fender clearance.
