I haven't changed the suspension. I'm thinking about different spring setup because I like the raked look, and even an 1" higher it would look better. My tires cleared the springs by a little more than an inch, and I have lower wheel wells since mine's a '68 Dart, so that is literally the largest tire I can squeeze in there, and this is stock springs in stock location.
They're plenty wide as far as looks go, plus I'm only pushing mine with a turbocharged slant, so I don't really need a bigger wheel I'd think.
Plus my springs are sagged, hence the shackles, which just evens out the body so it doesn't lean over as bad.
