Pro-kit a good choice, very subtle drop compared to some but it’s the look I was going for. Still has that factory appearance but something looks different... better.
Mine have been in almost two years now, no CC plates, one alignment still within spec last time it was checked. I had Ford C-springs in a 00 GT with factory struts/shocks, no CC plates and it was fine too. A lot of people run factory struts/shocks and don’t have a problem. Depends some on the kinds of roads you have to drive, if they are smoother less problems but aftermarket struts/shocks are worth the expense.
Get a buddy to help, it’ll be easier on you. It’s not that complicated of a job to do, it’s more of a use jack stands and a good jack kind of thing. Get the car up high enough you can lower the front and rear far enough and the springs will all but fall out. You go to prying and yanking on that spring and it wont feel good. Take your time, be safe and you and your buddy will be on the road in hours.
Good luck with it.
