![]() ![]() So for us it seems pretty safe to ignore KPI in thoughs about camber anyway. So just using those formula with a 5 degree steering angle -Ĭamber from 7 degree KPI. So my thought is that if you have 10 degrees of steering angle on a large radius turn that would mean the back tires are unable to generate much force because they would be running at 10 degrees less slip angle. When road racing and in general use the turn diameters are larger. If you race in parking lots and have small diameter turns in mind, then more steering lock becomes important. ![]() This would be for road racing and general sporty driving cases. What I'm thinking currently is that mostly what's important is pretty small steering angles, perhaps 5 degrees for a round number. I have also seen oval track spindles with multiple holes for the top ball joint that can be run as 5.5 or 10 degrees of KPI. The Mustang II spindles are available in 7, 10 and 11 degrees of KPI. I've been trying to firm up choices of spindles on my project. Warren thanks for posting these formulas. ![]() The columns are cambers at various roll angles: 0,1,2. The first column of each table is steering lock: 0, 5, 10, 15 and 20 degrees. (My apologies for the unformatted Table, but I wanted to put it in the message body. Being a Naval Architect by profession, the only value in this table for which I have an intuitive appreciation is roll angle! So, the question is: for those of you who have done this before, do my resulting cambers for the outer wheel look reasonable? The inner wheel seems to be a dead loss, but that seems consistent with everything I’ve read. These values seem to be in the ballpark for Miata and Corvette according to ‘Steve’ in my earlier post where I reported his formulae. The calculations are based on 7 degrees of caster and 10.9 degrees of kingpin inclination. Following are the results of my string computer exercise, including the effects of steering lock, using the formulae for camber induced by caster and kingpin inclination according to my preceeding post. ![]()
