If I remember correctly I think there's a fitting guide on youtube. I don't have access at the mo or I'd find it for you.
Dumb question, but whats the importance of the washer. I got some protectors, and it is a much better fit without the washer?
We get supported by GB Racing as an Army road race team so I'll be ordering a set soon for the R6 at a heavy discount. Highly rated bits of kit that do a cracking job.
