Hello, so I am thinking about upgrading my stock alt to a Mechman 270 amp G-series. The issue that I have is where my alternator is located, it makes installation extremely difficult. My buddy who has a high output alternator is constantly needing to replace his belt (once every few months) and doing that on my car would be an all day job. I was just wondering how often everybody else's belts last, because it might just be his car that's the issue, and I don't want to upgrade my alternator if I'm going to have to replace my belt all the time.
