Default Aftermarket Wheel Question

So this goes out to the guys that have aftermarket wheels. I currently have aftermarket wheels and went to try and change my set up to a more aggressive stance and these suckers just wouldn't fit. How is everyone throwing 10.5' wheels in the back without rubbing? I am lowered so take that into account. Here are the specs I am looking at

Front: Tire (245/35/20) 10" wheel +40 Offset. This fits fine without jeopardizing the fender but they did have to add a 5mm spacer just to clear the brake. Wouldnt fit on it without the spacer with this offset.

(Current front setup is 9" wheel with +35 Offset)

My main question is the rear.....

Rear: Tire (275/30/20) 10.5" wheel +30 Offset. Took a few pictures. The car is lifted on the lift but when it is sitting there is no fender gap front or rear. Maybe fit a pinky in it.

(Current rear setup is 10" wheel with +40 offset)

What am I doing wrong?

Current Setup

In the rear, you're sticking out 16mm more than your current setup. 20x10.5 should be +45. See this thread:

You should use this site for calculating offsets:

Do you have a pic of the car on the ground, shot from the rear to see how much it's poking?

You just need a smaller tire. 265/30 from a toyo or Falken. 255/30 from everything else. Either that or get camber kit so you can dial in camber.

I run 20x10.5 +15 255/30 in the rear. I drive on air very low with no rubbing whatsoever. It's a mild stretch.

275/30 tire and +30 is probably the limit for these cars. It was the limit on a few of my previous car before you needed to start trimming bumper brackets and or camber, etc.

This^^^

When the car is sitting on the ground, the wheel should naturally camber into the fender. Will it be cambered in enough?...Won't know until we can see pics!
