I've never heard of that. I would also certainly think you'd begin hearing an audible tick if something was going bad.

I was reading that last night as well and I think something is wrong with that answer as well. I had a set of 1.7's for 35K with no problems or wear issues, and my 1.6's with 18K on them look new.

What about the Helix TB spacer in the Mustang section advertising 20HP? Jim what do ou think of that?
