well i was looking for coilovers for the 929 today and came across these and thought that they would make a good alternative seeing as ther is really no options for the HD series, they cost a bit but seeing as most coilover kits cost about 1200-1800 and there really are no for our cars i can figure that having the ability to adjust ride right and stiffness it would be well worth the cost!
