Hey guys, Im new to the modded cobra scene and need to replace all of my stock pulleys and belt. I like the BF pulleys, I think a lot of you guys are running them too. The kit comes with 3-100mm 1-92mm and the bracket for $294, not to mention it come in RedFire!!! two questions (1) Is this a good kit? (2) why are there different sizes and which ones go where. I know the question is prob dumb to some of you but any help would be appreciated, esp as to why there are different sizes and the use of the different one. Thanks:shrug:
