I had Brembo's and then switched to six piston 15" StopTech's. It was mostly for looks, because I switched to 20 in. Forge Star's. Like most have said, if your not making repeated stops, or racing, pads, fluid, and tires are plenty. You can improve the feel more with some braided lines.
If it's somewhat for looks, make sure you paint them, and use some Brembo decals. (eBay)
