159 TI too low

[Colin Edwards]

Fair chance corrosion is the culprit.  And fair chance pommie salt accelerates the corrosion.
Likely failure location would be the transition point between bearing coil to first active coil.  That wedge shaped environment would probably concentrate moisture on and about where the paint is eroded from the bearing coil seating surface. 

Do Ti springs feature less metal / lower active coil count than a "standard" spring or is a Ti spring a "standard" spring set shorter?
