slngsht Posted March 27, 2007 Share Posted March 27, 2007 I'm about to do a change of front uprights and A-arms in the next couple of weeks. Obviously since I have the car and the uprights, my hands will be tied as to what I can work with. But before I start, I'm going to analyze it, and make sure what I'm about to attempt isn't going to screw things up. My questions are: 1- How much movement of the roll center is "normal", both horizontally and vertically? From what I had read in the past, ideally the roll center needs to be above ground, and below the rear roll center? I could be totally wrong on that. 2- How much camber change is reasonable (i.e. at what point would it be considered a reasonably good setup) - as a function of roll or dive. I'm already aware of making sure the motion ratio for the spring should stay linear, so I'll be working on that. Any pointers welcome. Link to comment Share on other sites More sharing options...
sb427f-car Posted March 27, 2007 Share Posted March 27, 2007 I know front roll center should be about 3/4s of the rear roll center? So your statement/question about it being below the rear's is correct. Ideally, from what I have read/understood from Staniforth's book (competition car suspension: a practical guide, 4th ed., good reference and a must read before building), is that as low to the ground for roll center as possible?
