i did a 2.5" drop in the front and 1.7" drop in the back with some tein springs. do i need a camber kit for it or no? it's about 2 finger gap in the front and 1 1/2 in the back.

 

Not necessarily. A lot of people here including myself tuck tires without F/R camber kits. Just an accurate alignment, set the toe to zero, and proper rotation of tires. If you have directional tires, make sure when you criss-cross them to flip the tires so the arrows are pointing to the front.

 

no needed for a less than moderate drop. Like stated above, some rides are slammed and dont even jock them.
