What's the normal range of the king pin angle for desert racing trucks/buggies?
I read Herb Adams Chassis Engineering and he suggests running a smaller KPA because the KPA affects the scrub radius which he states should be as close to zero as possible. . .I know the book is written with asphalt going race cars in mind but it's about the only decent suspension design book out there (at least that I'm aware of. . .if there's another one someone please let me in on the secret). . .I'm sure that off-road vehicles have different needs than road going ones, but today is the first time that I actually saw a KPA listed for a desert buggy and it was 14*. . .which to me seems like a lot. . .
So back to my question. . .what's the normal range of the KPA and why?
Thanks!
