I'm looking at a BBK and most kits include a 6pot front + 4pot rear combination. From reading some threads here, there are some who said the Evo uses mostly the front brakes anyway and its pointless to upgrade the rear brakes. If that's true, wouldn't I be better served by just upgrading the front to 6pot?

There are many kits but I have shortlisted Alcon and Endless.

 

First, forget 6pot vs. 4pot. Number of pistons doesn't really mean anything about how powerful the brakes are. They're more about pedal feel.

Many kits send too much bias to the front of the car, which is a problem because the EVO already has too much front brake bias in my opinion. Sending more to the front with a poorly designed kit will lengthen brake distances.

Alcon preserves the stock bias while Stoptech's BBK actually sends a little bit of bias to the rear if i recall. I believe the Brembo GT BBK also preserves stock.

I'm not sure about any other kits, so I would choose from Stoptech, Alcon, or Brembo. I'm inclined to believe something is crap until they prove to me otherwise, because most of the time it is.

Between Alcon and Brembo GT, which would be your choice? Also, would installing an adjustable brake proportioning valve and sending some brake bias to the rear be beneficial?

 

Definitely helpful to install a prop valve, but it sure is a lot of work. Overkill for a lot of people. Would be a lot of fun though.

Tough call to choose between Alcon and Brembo GT. I might go with Alcon.

On the Alcon, which rotor size would be better to use with 18" wheels? The 343mm or 365mm?

 

If the 365's fit, I would go for them. From your mod-list it sounds like the right choice.

A few months ago Sport Compact Car Mag. did a big article on big brake kits. Unfortunately it was on a new RSX but still the principal still stands. Cars and bikes are 99% all front brake bias. Most all the kits out actually make this worse. You really have to spend alot of money to actually improve stopping power/distance, so their test showed. All of them actually lost stopping distance yet a couple actually improved brake fade by using a bigger area. They as well as many other articles actually show it to be more of a show/full race mod as oppossed to a good street driving mod.
Why don't you lust get a set of good slotted rotors and a set of really good pads if you want to improve stopping power? Just my .02's

 

Do not forget tires. If you want to improve stopping distance on any setup then stickier tires are a must whether you're on a stock setup or something aftermarket.

With that being said, you also need to consider what you're trying to fix. Fade or stopping performance. If the warm/early lap performance makes you happy then try and get more air to the front rotors (it's a heck of a lot cheaper to start there first).

If you're looking for overall improvement, and you've taken pads, tires and cooling as far as you can then start to think about a BBK. If you go this route then I would strongly suggest going with a known, and respected name in the braking business.
