Vert springs and coupe springs have different rates... you can use coupe springs in a vert... mine is dropped a little over 2 with eibach sportline springs... is this about the height your looking for???
I used progressive Eibachs from a Fox 'vert, and it gives a smidge more drop w/out much scraping.
And I use Tokico 5-ways set on 2 for a great street ride--best of both worlds.
they're, of course, saleens (authentic..not that it matters much)
Right now I'm running a 265/35/18 up front and a 285/35/18 in the rear. I'm running falken fk-451s right now. No real complaints...just not enough traction in dry weather...but awesome traction in wet weather.
It's getting to be time for new tires though so I'm thinking about a set of nitto 555r's
on a side note, I've always liked DFG cars. Just add some shiny tips and blacken the taillight bezel up a bit.
