You're missing an option for the poll: auto-set via the spring loaded tensioner (that's what I've been using since 2008 and over 120,000 miles of daily driving)

Seems to be work fine. I do take the tensioner off, clean and lubricate it before installing

How about machine pistons or order custom with valve relief and make non interference?

Water pump pulley twist method for the cambelt. Just replaced the belts and pulleys for the 2nd time in 20k miles/10 years.

My auto tensioner always over tensions my belt. I have one of the early arnworx tensioning tools before he switched to the one that looks more like a 9201. Works great, with no complaints here.

So for the people who don't use the factory tool or the Arnnworx, what do you do for the balance shaft belt??

I've compared the spring tensioner on my S2 against the result using the P9201 tool and it's been "close enough." My new belts are due for a recheck soon and I'll make another comparison to see if it's still good.

Nice. I'm not saying all tensioners are bad, but I feel like relying solely on something like that when literature doesn't say to do so is potentially asking for trouble. I'm sure with the manufacturing variance in springs, you can check to see where the tensioner puts it, but to say they all put it where it needs to be is a little too trusting IMO.
