Ok, the shimming of the spring on my van resulted in an improvement in traction. Subjective?, hell yes. I have no lap times to gauge against, as is the case when you change a suspension setting on a race car. I do have the same driveway (about 1/4 mile of gravel at about 6% with a few pitches at ~10%) that I've been driving up and down for a year in the van. Now, I have less tendency to lose traction on the steeper sections, even if I don't 'get a run' like I have been doing. Also, the wheel that I shimmed (right rear) doesn't start hopping over the low spots... I think I've made a move in the proper direction, trying to add some of the vehicle's weight to that corner by shimming down the spring seat about 1/4", so far... Subjective, until I take the Van to the Nuremberg Ring or Laguna Seca and cut some laps.....NOT! Don Hanson |
