The increased camber at a lower ride height is simply related to how the tire travels through it's range of motion. If you lower the car, you will increase the negative camber on the tires. If you want your tires to last, keep the camber within stock specifications.

I had a 1" drop with the Prokits and as I stated above went from -1 degree to -2.1 degrees of camber. The camber links put me right back at -1. If you drop further than that, your camber will be even more negative than what I experienced.

 

myself i wont lower my car. my car already bottoms out . if i lower it i wont have a bumper for long.
