In the end we went with 500/800. I was running KW CS, and it seemed 500/800 was not a bad combo for dual purpose car, found it rough for daily use though. Expecting the JRZ shock when set up right should handle the spring rate for everyday use with no issues.
You find your car neutral??
What size RS-3s you running?
Hopefully when I get my 550 springs in I can give you a positive response. Someone on the forum rode in another person's car with JRZ RS and said the setup tried was very capable of handling daily road work.
R-S3's are 275/35/18 all around. Ran a 265/35/18 front and 285/35/18 rear before, but experienced a bit of under with that set-up. I'm liking the square set-up better.
