I have the Calmini 3" kit, only thing i dont like is the Squeak... I would suggest if you go with Calmini, have the UCA drilled Tapped and add a grease zerk fitting... the RC UCA's come with the Zerk installed.
I too liked the fact it was a Kit... UCA's, T-bars are a little stiff, rear springs and drop down bracket.... I might go as far as to suggest using the original T-bars...
