20 inch rims and lowered cars

Here's some pics of my 95. I have it lowered with the eibach pro kit, but I think I still need to drop the front maybe an inch. But my front is so freakin low already, I might not have a bumper for much longer if I lower it anymore....
I still love the way the 05's sit with 20's. I've seen a few dropped and yes, they look better, but I'm not sure if it's worth all the hassle. They still look great.

Oh, and you can't beat the deep lip that you can fit on the 05's. I'd never be able to go that deep with a 95! .................so jealous........

Nice ride sick

Anyone have a good site for rims that will fit the 05. And I'm not talking tirerack or discount tire direct, I want some nice rims with a deep dish.

What are the offset requirements?

The only place I've seen a selection of deep-dish rims was mustangtuning.com. Most of them were bullitt style, but they looked great!
