I HAVE BEEN REVIEWING ALOT OF INFO ON SUSPENSION LIFTS ON THE NET AND ALSO ON THE MESSAGE BOARDS AND CURRENTLY SERIOUSLY LOOKING INTO GETTING ONE FOR MY F-1!! JUST WANTED TO KNOW IF ANYONE OUT THERE HAS ANYTHING BAD TO SAY OR ANY OPINIONS ON PROCOMP LIFTS OR ANY OTHER BRAND THEY INSTALLED THAT WAS EASY, WITHOUT LITTLE OR NO MODIFICATIONS NECESSARY?? ALSO MAX TIRE SIZE TO FIT WITH A 4" LIFT?? 35'S MAYBE??
