I have two questions please. How far can I lower my 01 before I need CC/Plates, and when do you start to get bump steer?

 

2" or more

 

I did BBK lowering springs, supposed to be 1.5" and I didnt do CC plates... However ifyou look at my wheels from the front they show a lot of camber, but my tires dont really tell the tale of having alignment issues.. I will get CC plates eventually...but you can get away without them

 

you can get away with up to 2", at 2" you might start running into problems. anything from 0-2" tho you should not have a problem
