Pro gears vs street gears

I have, obviously was told by the sales rep at Strange to not run them but I did and they have been fine. I guess what his warning was that they are softer and so will wear much quicker and ultimately fall out of initial adjustment and become noisy too. I was ok with replacing them on a more frequent basis than regular gear sets if needed be for the extra assurance at the track.


How many miles did you get out of them?
