So you had the "135" factory SSK installed on your 1M ? Could you give us some feedback about cost, man-hours and feel ? Thanks, Dee-Jay.
Sorry for late reply. I think you can search ob forum on step by step instruction fir DIY. I paid mine only $90 from my local dealer and installation not more than $20 for labour. Feel: first and second a bit tight third and so on are sex.
Hope this will help
