New Brake Job Options

[DIONYZUZ]

Hey 6gc,

I wanted to know what else I should do with the new brakes I got. I got some Brembo Blanks in the front and rear and the ebc redstuff brake pads all around, SS brakelines, and I'm going to paint the calipers. I'm waiting on the rear rotors because they are on back order, but in the meantime what should I get? new pins or other parts? I was originally going to do the st205 brakes, but I gave up on the idea and just went with this. I've never replaced my brakes before, so any advice or suggestions will be greatly appreciated.

yes, i've read that a few times already, hence why I bought the mr2 turbo calipers.
this is what i got out of it:

Damn so the brake bias gets shifted to the back that's no dice at the track. Although it will take less effort to lock the front up.

not nessesaraly, the " theorical " magic number for brake bias is 60 / 40 ( front / rear ) but that will vary from setup to setup, and the importance of modifying your Bias is to use the most grip available while keeping the front locking first than the rear, so if you think about it, as long as his front is still locking the tires before the rear, it is an upgrade, a good one actually, because it will spread the braking force better among all 4 tires, so all 4 tires will work more efficiently at stoping the car instead of the front ones doing most of the job with a 70+ % of the braking force on the front.

One of my friends tracks his car every season and his brake bias is 58% front 42% rear with an adjustable proportioning valve, he got to those numbers after a lot of trial an error testing. so Norberto, find a safe area where you can test your brakes, have someone look at your tires ( or video ) and make sure your front tires lock before your rear one, if they do, I'll be the first one to call this a great upgrade, best bang for your buck brake upgrade.

of course, a car should be setup to the driver's taste, but my point is that, This " upgrade " should be called an upgrade. in a perfect world you would want all 4 tires locking at the same time as this would make all the tires work just as hard stopping the car, but in the real world the front needs to be locked just slightly before the rears, so depending on the weight transfer due to suspension and engine position and of course drivers taste we should modify the bias to make the best out of the setup,. if you look at most adjustable proportioning valve setups they are use to lower the bais on the front not to increase it, as manufacturers go for a very safe number making sure the front will locked up before the rear even when we are using crappy tires on the front. so for race / track where tires will be properly maintained they aim to bring the bias closer between front and rear while still keeping the front locking first.

let me hear what you think, as this is not what " I know ", is just what I've understood from some reading I've done and I can be very well misinformed or have misunderstood the data, so some of you should support / contradict what I'm saying so we can all move in the right direction.
