well i wasent sure if you was just going to use it for a daily only, those mods do make sense if you plan on tracking it. the slotted rotors will provide a better cooling but you have to take into consideration of the heat ranges of the pads, if they work better at a higher temp then you just hindered there performance by keeping them too cool, your better off with just better pads.

the brake lines are not going to increase pressure and response if the inside diameter is the same...which it is (goodridge), again just for show. and the oem brake fluid is good enough for track use unless your doing hardcore track races and have to race back to back.

Im just trying to help you get things that will apply best to what you need. i just figured you was going to use it for dd and autox every few weekends
