With the coil-over configuration you have a higher motion ratio so you get more effective spring rate at the tire with a lower rate spring on the shock than you would with the spring in the factory perches. A 375#/inch spring around the shock yields the same 260#/inch wheel rate as an 800#/inch spring in the OEM perches.
my comp set up was like 600lbs front and 800lbs rear

there are about 150lbs less
