Usually the spring rate number is on the spring itself. I bet a call to ridetech will verify what ones you were sent. I originally had 650s on the front but replaced them with 700s after my first autocross. The 650s rode great on the street but after my first autocross I was concerned with no adjustability (up- ore ride height) due to running out of threads. After swapping in the 700s and they sent me another lower mount (the part to goes between the spring and the nut) that gives you more (space). I haven't notcied any ride difference between the 650s and 700s after going a couple of clicks softer on the adjustment.

Just curious, what is the measurement between the ground and your subframe? I have about 4.5" and my headers hang down another .5" giving me 4 inches of clearance. I have not had any clearance issues in normal driving. Another thing you might look at is how are your motor mounts bolted on? There was a thread on this board about depending on how they were orientated your engine would either sit higher or lower. If I remember right, if the mounts were installed with the single bolt up and the 2 bolts down, the motor would sit higher (giving you more header ground clearance).
