Lift and headlight aiming

My 5100's are on the way, going to set the fronts at 1.75 and a 1.5 AAL in the rear. I have a topper on and the truck seems to set pretty level now with the stock suspension, but seems to bottom out in the rear on bumpy roads. Am I going to have to re-aim the headlights to keep from blinding people?? I get bitched at now by co-workers saying my lights blind them. I run silverstars, and they are quite bright.

 

Is the first half a question or a statement about bottoming out? I got confused. With the aiming of the headlights I would say re aim them because I got sick of people flashing me. So I did.

Edit: Nevermind I just re read it, I confused my self

 

Yeah,note to self not to post half asleep! Meant to ask with the 1.75 in front and 1.5 AAL rear w/topper will I need to re aim, but you answered. Thanks!
Sorry for the confusion

 

Ya, I was half asleep as well. I dont know how big of a difference it will make with the 1.75" but I know with the 3" it was a big difference. What I did to check it was parked my truck in the driveway then drove another car up like a passing car.

 

Haha I did the same thing! I parked my truck and corolla facing each other and sat in the car to see if I was aimed too high!
