The camber is for a purely daily driver car. I like a good back road and currently I'm seeing some additional outer tire wear. Back in the day I was able to get about -1.75deg on my r53 mini with some ireland fixed camber plates and that was great on that car. The extra front end grip and turn-in is what I'm after, with more even wear of course.
I'm able to get -2.4 with Eurosport's camber kit, 1" drop and a little slotting of the mounting holes.
They add zero NVH, so they're fantastic on a street car.
