Pulling this thread back from the past...

I bought a set of OTR 525 sprockets for my 660Z. I hate replacing chains and sprockets and the fact that I do about 2500km (1550 miles) per month this can get costly too.

So is the DID ZVMX a better option. Will it last longer between services. My current chain, JT 520 has a few stuck links and badly stretched at 17000km (10500 miles). Not very happy with the JT chain, so I am going back to DID.

VX2 or ZVMX?
