when i lower my 2001 prelude i am going to lower it at the most 1.8in do you guys think i will need a camber kit?

1.8 is borderline.
You can go with one or go without one.
usually more than 1.8 is when usually get one.
So I say you don't have to, but its more of a personal preference.
If you want to drop it any more than that I suggest you get one.

thats what i thought to but i just wanted to get another opinion besides mine.

Getting a camber kit isn't about personal preferance no matter what the height. It's about not wearing out your tires in 6 months. You need to get it aligned and if the camber is within specs, then you don't need it.

im at 1.4 on h&r sports and im borderline out of spec's (negetive 1 degree) on my 5th gen lude. 1.8 will deffinatly have you out.
