Any Diffence in Big Brake specs between UDM models?

[Akhie]

Dear Sifus and Tech Gurus,Sorry if this question was asked before elsewhere but i cant find any mentioned in my searches.I noticed in the online parts store, there are various big brake kits for different models. Are there differences in specs between models? What I saw, the rotors and caliper sizes seem to be the same. Are the different kits classification due to the brackets and holders, or whether floating or not? Or is it due to something else?Appreciate your views and thank you in advance.Regard, Akhie
