The calimini's are great, but if you go through xterraparts they sometimes take longer that if you went straight through Calimini. A fellow club member order some Calimini shackles through xterraparts and got them after a delay and then they were missing parts resulting in a trip to the hardware store on mod day. I heard that the people at Calimini over the phone are great. Spencer Low Racing make a good shackle too but their order process and customer service have little to be desired IMHO.
