Fixed Negative Camber
« on: June 14, 2019, 04:49:50 PM »
On your axle, if using top and bottom heim joint (spherical rod end) why cut the axle with a fixed 10* of negative camber? Isn't the whole reason you spend a extra money on the heim joint is to set that adjustment manually? Seems like at max go with 3*-5* fixed camber and use heim joint adjustment there to get the exact KPI and camber you want. I was thinking of leaving the axle ends square and using the the heim joint to get the KPI and camber I want. Am I wrong here?

Thanks for the response. I have read that write up, and read a few engineering journals on it for on road vehicles. Also some great videos on youtube by SK8215 who is pretty much an engineering genius. I don’t agree with georges write up about camber. The OEMs do it, look at the new Craftsman tight turn mowers that now have ackerman steering and negative KPI. Having a large scrub radius in turns on dirt and grass is not a good thing. Agree with him we’re running bias tires so there is a difference. At the end of the day its probably splitting hairs on something like this. I’m going to build mine square and use the chromoly heim joints to get the camber I want. I dont see any advantage to fixing camber negative if using rod ends on your spindles.

Sure, but I wouldn’t contribute those wins to 0* camber.
