Totally agree. On a 2dr, I don't feel you "need" more than 2.5" for 35". Might want to do a fender chop or get aftermarket for greater clearance. Once you go higher than that, as
@Danarch said, the add-ons can add up.
Also, I absolutely concur with getting proper rims. I'm one of those that feel using proper wheel spacers can be done safely, but if you're doing it
right, get the proper rims. Shoot, you might even find some decent used ones. You could also go the pizza cutter route, but that's a different topic
