would like a little more insight on some good brake kits for my 03, any suggestions/expeeriences would be great

Are you looking for racing or just something better than stock? For daily driving I would recommend brembo blank rotors w/hawk hps pads. For racing you can go with cross drilled or slot rotors with hawk pads.

You could upgrade to the 05 maxima brakes... There are threads on this...

Depends on what you want. You have three choices IMO you can go with the 6th gen calipers and rotors. Blehmco's 2pc rotors with 2 piston calipers (http://forums.maxima.org/showthread.php?t=437932). Or Jeff92se's 13" Cobra Kit (http://forums.maxima.org/showthread.php?t=444504) It all depends on what your looking for

As Grey is saying you can upgrade your pads and rotors. Also, if you want performance out of your brake you can buy the braided brake lines and flush your whole brake fluid and replace it with some performance brand of brake fluid. 1. rotor 2. pads 3. braided brake lines 4. brake fluid performance brand. Remember that bigger is not always better.

without the proper components bigger is not always better.
