I have read the other threads here but I am still very much confused. I dont think i would need the rear drum to disc upgrade as I do not have that much HP to start with. I just want to be able to decrease my stopping distance. I have Carbon metallic brake pads but it is still not enough. I want to go slotted or cross drilled and i heard the pros and cons. Which are best for mostly street use and some race use?? I know the NX2000 discs are bigger and was wondering if i buy the disc, calipers, etc. for the NX2000 say slotted, can they be plug and play??
