KT on grocery getters yea its cheaper to produce and works.. but it is not on performance cars and not a techonological performance upgrade. its a bigger pad, but not a superior brake design. many modern performance cars use multiple pistons... 6 or 8 even. |

You can make up your own cooling for 4 lug rotors and then run the Raybestos ST-43 compound. There is nothing nearly as good as the Raybestos pads.
Also, Chris Foley used to make ducts that went over the front calipers and forced air into the pads. Might be worth asking if he could do them again. |

Yeah, can you fit them under 15" rims with stockish disks? 4 lug? All the design constraints considered, it seems to be a pretty elagant solution. |

Trekkor, do you have a brake brace in your car? You should take mine out for a spin tomorrow. Stock brakes, 19mm MC, brake brace and hard as a rock.

Just read this thread on a Subaru forum talking about Floating vs. Solid caliper design. They get a little off topic (duh, it's a forum) but what I took away from it is:
- Potentially the floating caliper design has less ability to modulate near the threshold. - Potentially the floating caliper has more slop upon initial engagement due to the number of connection linkages to get force from the piston applied to the outer pad. All those little gaps and movements need to be closed before the pads even start to grip. Of course, neither of these points have much to do with the ability for the caliper to simply stop the car. That is undebateable. And the way I look at it the solid caliper should have better 'feel' all around, but if you can drive fast with a floating caliper then you've got nothing to gain by going solid. |
