Im wondering if I use a a 1" m/c and brake booster with my stock civic brakes the 9.5" ones if it will be of any benifit?

 

itll basically push more fluid, so it will take less push on the stock pedal. so if ya wanna firm up stock feel, itll do that, but it won't make your car stop any shorter. if you want a firmer pedal feel, try stainless brake lines first. also, what helped my 9" brakes was regular brembo rotors, and AEM's ceramic pads. They are the bomb.
