These TMS front Bilstein J-Stock inserts are getting harder to find and obtain, but are available here:

EDIT: These are of course rebuilt by ECS/Turner, so you could also have your worn-out B8 Bilsteins rebuilt for $125 (ask for P36-0335JS valving) but for those who dont have rebuildable B8 cores, these are great! Not 100% sure the B8 and these share the same shorted piston though (which IF different would add to rebuild costs)...
