OEM, versus the available aftermarket kevlar one, Greddy, HKS, Power, etc. What are your thoughts? I see a lot of the tuning shops using the aftermarket ones, but some people on here don't like them. Please give either an educated or experienced response.

 

The OEM one is just fine. You cannot go wrong with it. Although this time around on the Evo i chose to use the HKS Kevlar belts.

 

I'm just concerned about making power and the stock belt "failing" ...on the other hand, I'm also concerned about long term effects of the aftermarket belts. My Evo is my only car right now, so I'm just being a bit cautious. Anyone been using an aftermarket belt longterm?
