-1.5 WONT kill tires
that's a MYTH
bad toe WILL
thats why after you lower cars you GET AN ALIGNMENT, primarily to fix that toe which will just murder tires
now camber ipersonally say beyond -3 then you'll REALLY notice wear
many of my friends use -2 or so daily and no unusual or obscene camber wear. -2.5 is ok too, but i say -3 or more, it will wear much faster, especially if you go on the track
UCanTry: pillow ball mounts
no, rear is pillow ball and you CANNOT adjust rear camber via them.
fonts need camber plates
rear needs upper arms
stock has a eccentric bolt, i THINK there are aftermarket ones not sure. but rear upper arms will get it back to 0 degrees or up to -10 or more im sure hahaha..
