To be honest, I actually didn't know the difference was negligible. I knew shocks were the primary culprit for a harsher ride but I always figured a higher weight spring had to factor in.

Ok. So you're going with a best of both worlds approach. I assume you don't do a lot of city driving? I'm actually considering going to 1.5 turns from stiff on the front (from 1) and 2 turns from stiff on the rear (from 1.25) and keeping it at 3 clicks off of soft for the street. The roads are absolutely brutal around here.

We sure do have a ton of caster! My friend who works on BMWs and Impalas always gets a kick out of our 5.5-6deg versus their 1.5.
