Sportlines are $171, and about the same drop as Progress. As for a camber kit, I would definately suggest one for the rear, however the front really isn't nessicerry (although, considering the SPC kit is only $135, it doesn't hurt to get them). About the progressive rate, just about any spring you get for street use is gonna be progressive rate. Solid rate springs are mostly designed for track use, and would provide an extremely uncomfortable ride for daily driving.
