re: Upgrade Brakes
Ok, now for my 2 cents worth. I went through this same delimma several years ago, and here's what I came up with. Unless you are doing some serious autocrossing you don't need cross drilled rotors for a street car. Not only are they notorious for stress cracks in the vent holes, but when you actually think about it your reducing the available braking area by adding holes in the rotor. Your car will actually brake better and shorter without them. If you want better cooling and fade free brakes I say get them cadmium plated (prevents rotors from rusting, thus making sure the vents work at near optimum efficiency all the time) and add a flexible brake duct from the front bumper to cool them at speed. Slotted rotors arguably will make the car stop a little better, but the increase in brake dust and accelerated pad wear is why I decided against this option. As for oversized brakes, sure they look cool and will help the overall braking of the car, but their high price, and the fact that they add a decent amount to the unsprung weight of the car (making it accelerate a little slower) is why I decided against these.
My set-up is as follows: I went with plated Brembo replacement rotors (they are a little oversize I'm told, by a mm or two), Goodridge stainless steel brake lines, upgraded synthetic brake fluid (Dot 4 or 5 I forget, as opposed to the typical Dot 3 which has a softer pedal feel and lower boiling point), and Carbon/Kevlar KVR brake pads. All these items put together makes the car haul down speed like I have a shoot attached to the back of the car. It was amazing, and the pedal feel went from sorta soft and mushy to rock hard, even giving me informative pedal feed back which was lacking with the stock set up. To prove the effectiveness of these mods I did some brake testing after everything was installed and broken in. I got my 15 year old car (at the time) to brake better than 98-99% of all the cars in the car magazines, exotics included. I got a best 30-0 distance of 29 feet, bested by only two cars at the time, and tying another one. I decided not to try the 60-0 tests as I felt this was a little too dangerous to be doing on public streets, but I'm positive I still would have rocked more than 90% of the cars in the mags. And if/when I ever decide to do some serious track racing, I'll add some brake cooling ducts to the fronts, which should ensure fade free braking for most of what I'll throw at the car.
Like I said this is what I've done and had really good results with. Hope it's helped you out in deciding what's best for you. Good luck.
