I used kartek, I started ordering through poly but kartek had better prices and cheaper shipping at the time. I also think 70 is a very big compression stack that you may not use. You can buy individual shims if you're just after some of those.
The LSC unit itself, or a shim setup/shock mod that allows the LSC to work correctly? By that I mean does the tuner modify the LSC to work "correctly" in a general application or is he offering a whole package (revalve/modification to LSC/shock). I wouldn't mind shipping out and paying to make the LSC work, I don't want to ship my shocks out at this point.
My weight is fairly static anyways my thinking in the LSC was the tune that came with them would be close but not quite but since I'm revalving myself anyways I don't mind losing them.
Thank you for the insight either way though.
