I currently have project mu rotors/pads in front and was thinking about adding spoon calipers up front and get brembo slotted rotors with project mu pads for rear...would this upset the balance? If I remeber correctly bbk's don't improve actual stopping distance (depends on tires too)...so I was wondering if it was due to the fact most people only upgrade the front...?

 

Tires are what stops the car. If you want better stopping, get better tires. The only time brake upgrades really matter is if you tend to overheat them OR if you can't lock them up/engage the ABS when you press on them.

I'm sticking with stock rotors and calipers with carbotech pads. If I overheat them or wear them out early (which happens to carbo's when they overheat), I'll get brake ducks.

 

I see you have a FI badge so I assumed your boosting, upgrading brakes is a good idea, even if its just for the fronts since that what is doing most of the stopping.

 

A very small percentage of braking is done with the rears but there is still some percentage.

BTW...I'm not sure exactly which project mu pads you have but some of them have a lower co. eff. of friction than OEM pads. So if you feel like your car isn't braking like it should, it could just be the pads.

 

If you are talking braking distance, tires matter the most. That is where the friction limitation is.

If you are talking about repeated high speed stops, then big brakes, fluid and pads come into play.

Brake balance is important to maximize all the tires potential for braking. Whether or not what you're mods are doing who knows, it depends on a lot of factors. That's something you'll have to test yourself.

But yeah, if you put a big ass front rotor on with grabbiest pads, with not so sticky tires, big ass pistons with a lowered car (which doesn't sound like an odd config for the bling people) you're not going to be decreasing your stopping distance. If you want to read about it, here are some good whitepapers.

Waist of time and money. About the only improvmetns you are going to get over stock is looks.

The stock breaks are as good as it gets unless your building a specific car for the track.
