I am doing a brake kit group buy with Specialty Z right now so to give you an idea... I would email Greg at Specialty Z and as other people mentioned find out from him if a group buy is possible and what sort of numbers would need to be involved. It's kind of pointless to put out a feeler right now when a group buy may not even be possible. Do the background research first. If you check with SZ, than do a "feeler post" and you don't get a lot of interest just let Greg know the group buy won't happen and it's no big deal. He' s an easy going guy to deal with.
