Rear ride height without air shocks.

I like your 2nd photo better than the 1st. I'm not a fan of air shocks myself. If you want more of the stink bug look, I'd either get some new springs with whatever height you seek, add a helper spring, or put on some coil-over shocks. Keep in mind that some coil-overs have too big a diameter spring that will rub on the fuel tank. You may have to look at a few first to get ones that fit right without rubbing anything.
