i want to upgrade my enthusiast brakes. im going to put in some rotora slotted rotors, but am iffy on the break pads. im looking at hawk and endless, but theres is a $100 price difference. any good experiecnces with either? also, do SS brake lines make a difference? or should i leave the stock ones there? i want these brakes to hold up a day of spirited driving in the hills.. cuz i seem to do this quite a bit!
