I bought my front brake pads from ptuning.com w/the 5% discount for board members. The banner up there (top left) will change to ptuning if you hop around enough, just navigate through that link to get the discount! Enjoy!
Hawk is definitely one of the big players, but they don't make any rear pads (HPS or HP+) for the 02-04 SE-R. You should check out Carbotech Engineering, I know one of the guys who works there, Matt Nicholson who pilots a pretty quick b13 SE-R in autox, so they have a lot of Nissan applications, which is always nice in this Honda dominated world. Their products have gotten good reviews by users from this board.
I currently run Hawk HP+ up front and stock in the rear on TPM rotors, which is not very well balanced. HP+ is probably the most aggressive street pad you can get, they are very noisy, create an unreal amount of dust, but have eye popping stopping power. If you brake hard taking a sweeping corner, the car gets pretty squirrelly, the rear end actually fishtails back and forth. Not surprisingly, I'm asking for Bobcats both front and rear for my birthday present in a couple of months. BTW, I turn 30 maybe my wife will take pity on me and get me the Eibach sway set too...
I stand corrected, I really don't have my sh_it straight with brakes. What you listed has its own unique part number so I definitely think you're right. I guess I got it confused with the fact that they don't make a rear HP+ pad. You got me thinking though, one idea for me is to get the HPS for the rears and keep the HP+ on the front, it's a cheaper solution anyway.
