They provide over 3" of height adjustability at the joint and the spring. They were specifically designed for the 2GNT (either NT or FT). Without adjustment the shock assmebly itself is TWO inches shorter than stock and whle still maintaining full travel. They have 15-way dampening and stiffness settings. RRE had them created and, according to them, are THE Best for our cars. The color of the Coilovers are red and amber. VERY NICE. Their less expensive ones are like 1200-1500 I don't know for sure and are "only" height adjustable at the spring. Anyway give'em a call if interested.
