Spring suggestions?

For a car that doesn't see any road time. Maybe a sunday morning cruise.

can lower the car as much as it wants so long as long as i can cool everything suffiently.

must clear 275/40/17's all around

Hey Trey! I love my Ground Control coil overs and adjustable rear spring perches. My spring rates are 500# in the front and 120# in the rear. It gives you all the ride height adjustability you need. I use 275's on 9.5" on the street with no problems what so ever.
