The combination of Spax shocks and 97 Prelude front springs (360lb) are quite good. Little front end dive under hard braking and relatively comfortable drive. I am going to try the rear springs from the kit (300lb) next spring, but have to modify the spring perches this winter as the springs are 3" longer and will make the car sit too high otherwise.

The rear springs are a different story. They came from a 99 Mitsubishi Eclipse (190lb). I had to cut 1.5 rings from them to get the car to sit at the right height. This should have increased their capacity to about 220lbs. However, with new KYB rear shocks, I find them to be too soft when driving with the wife (small) and dog (big) sharing the passenger side. The extra weight causes them to compress too much at speed when hitting bumps in the road. They don't bottom out, but you can sure feel it. Will have to look for some 300lb springs for the rear.
