Hi Ray~

I'm not a technical car guy so I don't know quite what to say about the ride height. I understand that it involves swapping out springs to bring the car closer to the ground. The net effect (aside from looking much better) seems to be that the car is much more stable and "sticks" to the ground better, especially in corners. I also have the black diffuser kit at the rear end.
The interior is black leather.

Thanks, Brian
