so i was wondering if i have 20' axis and droped like 1.4 front and rear do i need spacers or camber or fender roll?

 

completely depends on the specs of both the wheels and tires.

also...

if you put spacers. you are pushing the wheel towards the fender which will increase your chances of needing to roll the fenders. and how agressive they are and how stretched your tire is will determine how much camber you should run

 

well i heard the stock camber cant handle it when u drop the car is it true?
