Civic Coupe Exclusive Suspension Tuning...
The Civic Coupe has the following exclusive suspension tuning compared to the 2006 Civic Sedan:
* Front spring rate increases 20 percent
* Rear spring rate increases 28 percent

Civic Si Exclusive Suspension Tuning...
The Civic Si has the following exclusive suspension tuning compared to the 2006 Civic Coupe:
* Front spring rate increases 17 percent
* Rear spring rate increases 14 percent

NOW... Based on this, we have to work backwards. The Si models have a spring rate of approximately 200 lb./inch front and 230 lb./inch rear.

Subtracting 17% front on my LX Coupe puts the front spring rate at about 170 lb./inch and the rear at about 200 lb./inch.

Comparing the LX/EX Sedan down from the LX/EX Coupe puts the approximate front spring rate at about 140 lbs./inch and the rears at only about 145 lb./inch.

If you cannot yet foot the bill for hfp, I'll sell you all my si suspension parts....
