NO! I installed my 5 point(only 4 point in right now till I get my seat in). I connect the lap belts to the factory seat belt locations AND kept the factory belts. I dont have rear seats so I took the bolt that held in the REAR seatbelt female side and mounted my shoulder belts to the hole where the factory seat belt went. I still have my stock seat in though, and I do not feel comfortable wearing them AT ALL. I actually never wear them, I still use the stock seat belt. But once I install my Sparco seat I will install my 5th point and use them all the time.
