Springs and Spacers
I wanted a stiffer ride than stock, so I tried the 600 lbs springs. I found they were quite harsh on the street, so I went to 450 lbs springs as a compromise. To lower the front end I cut the 1" thick upper rubber spring spacer in half. This 1/2" reduction ~half way between the fulcrum pins and the wheel lowered the front end ~1". This kept some rubber isolation between the spring and perch, avoided cutting the springs to maintain the spring rate and travel, and added some stiffness, all while lowering the front end.
