looking at buying a set of slotted rotors and pads over the weekend
just a few questions (ive already done a quick search)

is it worth upgrading to the DBA 4000 series over the standard DBA slotted rotor (ill be doing maybe 3-4 track days a year) worth the extra $$
EBC greenstuff ive herd nothing but praise about. except the road noise during daily driving. what about the red stuff pads?
also im looking at fitting them all myself. Easy enough job i assume. is there any guides out there to help me along?
Thanks in advance
