Keep in mind this is a 2300lb car!
Original Jaguar (4000lb car) rate is 250lb each at 10" length, I think on adjustable style they are 9". That however depends upon the shock being used. I used 250lb rate with great success and the squat was perfect. Removes the CCX perky butox as well. Stance was nice but hard cornering and a bump may cause a rub which is not unusual for these cars with the larger tires. Most of the time it was never an issue.
ERA and CCX recomend 350lb rates but for me that was too stiff. 250lb was perfect, remember that is with two per side unlike your new KMS! Good luck!
