Last night I installed the PDR 4k gov spring kit. When measuring the stock setup before removal, it seemed that one side measured less than the other, and also felt looser (both when pushing on the spring retainer washer, and when unscrewing the retainer). When I put the new ones in, I adjusted the one that started out tighter (measured larger distance, .060") back to where it was. The one that was looser, I put on one click tighter than it was stock, and contemplated going 2 clicks. When I started it, the idle seemed a tad higher than before, and smoother as well (idling ~900 now, was maybe 850 before; the higher idle may be the cause of the smootheness).
When I took it for a test drive, the first thing I noticed was that the bottom end is much more responsive; before it often had a bit of a stumble (particularly when cold) when starting in 2nd, which was really annoying considering the 255/85s and the Joe D clutch. Often times when you did manage a real smooth, non-hotrodding takeoff, it left a huge cloud. It seems way easier to launch. The bottom end is so much better now that it is almost touchy, I may go back in and loosen both adjusters one click.
Could the cause of my stumble have been uneven factory adjustment of the gov springs? Or is it the new springs themselves that fixed it? I don't think the difference is just the idle speed; I had it a little high to start with, to make takeoffs easier/smoother.
Tonight I get to install the valve springs (didn't have time last night); but on the test run, shifting at 3k, it sure made a difference.
