well, camber kit is really really easy, just loosening shit, and putting it back together. MAKE SURE YOU PUT GREASE ALL AROUND THE BOLT HOLDING THE CAMBER KIT TO THE ARM. Or else you will kill yourself listening to the sqeaks.
As for the coils, those are easy also, 2 people would be helpful, but i did mine the first time by myself. But take them to a shop to get the top part compressed off/on.
