I Lowered my Car using the Sportline kit for AM. Lately i've been reading about pinion angle. I'm looking to take it out on a cruise come July. My question is do i need to replace my UCA and adjust my pionion angle. Will not doing this damange anything. Looking for any opinions..

P.S ..I dont track the car it's a weekend ride and to go on cruisies with. however i do drive spirited every now and then.

 

I believe if the pinion angle is off you will end up with ruining the diff. There are videos from AM about what the pinion angle should be and how to measure/adjust it should you need to. Being that the drop is 1.5 rear you might be fine with the pinion angle.

 

I think the back was lowered like 2 inches

 

I will deff check out the videos on AM

 

If the angle is severe enough it can, most of the time improper pinion angle affects traction and driveline efficiency.
