I'm looking at getting a QS for my R6, and looking on the website I'm a bit confused.

Just wondering if marshy could possibly clarify a couple of things.

Firstly, it asks what length of shift rod is needed, how do we work this out? Secondly, there's an option to "add shift rod" and it has one particular option for the "R6 mod". What's the R6 mod, and if I select that, do I need to specify the length of the shift rod I need as asked in the first question?

Thanks
