I need help. I am going to convert a 91 LX 5liter car to 4 wheel 5lug disc brakes. I can perform the swap BUT I need suggestions and past experiences with the different types of this conversion ( SN95, piece meal salvage yard, catalog, etc). I will be running either 17x9 or 18x9 rear bullets and 17x8 front bullets if that helps. Also what is the biggest tire I can comfortably fit with this combo, front and rear, and a good set of progressive rate springs? Cost is a concern to some extent but you know,we all want the best most proven pieces, right?
