Some are built with 10 degrees, some straight. The most important thing is having adjustment. Look through the builds section there are tons of examples. Visit the parts provider web sites and see what they sell. You'll be able to figure out from there how you want to build yours.

I'm not sure what's negative and positive but I found out the hard way u must lay your spindles back. I went with 10 degrees on both sides with great results. I set my my camber so the tops of my wheels were laying in toward the mower. IMO this helps put the center of the tread on the ground when going hard in the corner with low airpressure. Low airpressure causes the tire to try to roll off the rim thus moving the outside tire tread to the middle. I run bigger front tires at a lower pressure to soak up some of the bumps cause I'm getting old. The camber is not the important and your choice, but u will not be able to steer without the caster angles. There are sum great write ups for these angles and more on this forum. Read them then read them again,lol
