1299 rear shock linkage bolt replacement I am in the process of upgrading all fastenings on my 1299 to A4-80 316 stainless steel. For the vast majority of bolts A4-70 or A4-80 is sufficient, there are only a few critical high tensile bolts such as front brake calliper bolts which need to be equivalent to grade 10.9 or 12.8. The rear shock linkage bolts (2 off M10 x 1.25 x 46mm long cap heads) - are these grade 5 8.8 bolts? If so upgrading to A4-80 may not have significantly high tensile strength. Torque value is 45Nm. These two bolts are located on the triangular rear shock half rocket arm. Options are: - upgrade to A4-80 316 stainless steel if these have sufficient high tensile strength - upgrade to titanium (probolt equivalent at higher cost) - leave alone, the existing bolts are not yet corroded. Any advice? Thanks |
I would go titanium as you know it will be strong enough, it's blingy and you won't have to worry. |
