I am installing them in the morning. I currently have my stock 19's on for the winter. How long should I wait before doing my alignment and since i have the 19's on, do i need to do another alignment when I put the 20's on or not?
Thanx Guys.

 

I would wait for a week, maybe ten days before I had it aligned. Hopefully
the springs are seated by then but it might not hurt to get it checked next
summer to be 100% sure.

 

couple weeks. you shouldnt need another alignment after 20s.
