Posting as a last resort. In regards to a 06 749s: are the caliper mount M8 bolts 15mm or 20mm in length? Please only post if you know for sure because I am spending a good hunk of change on Ti bolts. Cheers
Put a reference mark on the bolt and mount, take bolt out, measure. reinsert bolt, tighten to reference point. Go buy torque wrnech while waiting for Ti bolts to arrive. CDI maker snap on's and they are a lot cheaper.
