Gavin Posted April 26, 2007 Share Posted April 26, 2007 How much does a washer of a given thickness change caster? Quote Link to comment Share on other sites More sharing options...
johnc Posted April 26, 2007 Share Posted April 26, 2007 "I think" its about .5 degree for each .125" thick spacer. Quote Link to comment Share on other sites More sharing options...
Gavin Posted April 26, 2007 Author Share Posted April 26, 2007 Nice. I'm also trying to sort out how much caster I should run but am having some trouble. Right now I'm at 2.84 on either side. What are disadvantages of too much and how much is that? Quote Link to comment Share on other sites More sharing options...
blueovalz Posted April 26, 2007 Share Posted April 26, 2007 Based upon a 20" distance from the top strut mounting point to the center of the ball joint, you'll get about .36º of change for each 1/8" of change. You'll never get too much with washers. The disadvantage would be tire/fender contact in a turn if excessive, and increased steering effort, but that is a small one compared to the improved camber change in the curves/corners.

Gavin Posted April 27, 2007 Author Share Posted April 27, 2007 Cool. So, throw some numbers out there! Quote Link to comment Share on other sites More sharing options...
blueovalz Posted April 27, 2007 Share Posted April 27, 2007 I don't have any camber curves for the camber/kingpin angles that the Z has, but running in excess of 5º and sometimes up to 7º is not unheard of. I'm running the top end of that range, but this wasn't an issue because the bodywork was matched to the increased wheel base. Quote Link to comment Share on other sites More sharing options...
Gavin Posted April 28, 2007 Author Share Posted April 28, 2007 OK so I'll add 3/8" of washers and see how it goes. Thanks guys. Quote Link to comment Share on other sites More sharing options...
