I could not find the belts on ebay. I can say this. Mugen makes urethane belts (stock) and rubber optional belts. I had the original urethane belts on my car for months and they still look brand new. I changed to the rubber belts as they free up the car a bit. I have stripped a side belt and a rear belt, but even that is after quite a bit of running. The stock belts are just fine.
