what will lengthening my clutch pedal do

spring is close, so i'm dragging my belair out of hibernation shortly.

big spring project is manual transmission install with hydraulic clutch.

i currently have a camaro brake pedal in the car, and i had to extend the pedal arm down about 8" because of booster relative to floor situation in the camaro versus the 1950's car with the tall firewall. this seemed to cause no issues and my brakes work great.

my new pedals are also camaro units, and will install right in place of my current ones. i can pull the pin and put my longer brake pedal arm on, but need to extend the clutch pedal the same amount.

will extending the clutch pedal that much cause any negative effects with the master/slave, clutch feel, etc?

If you only lengthen it between the pivot and the pedal, it should improve leverage and make it lighter to press, the throw would be a bit longer but not much.

In this scenario there should be no impact on the rest of the system

Could possibly cause release problems.

Not gonna matter at all if the hydraulics are selected correctly.

I can't be the only smartass thinking that lenghening the clutch pedal will make it longer??.

Might need a return spring if the extra weight and/or angle are applying themselves toward the "in" action to keep it from slightly engaging because there will be more weight and more leverage but otherwise - as long as there is room for the longer arc... true enough. Same/same.

edit:

miss interpreted how you were modifying things...

Lengthing it changes nothing but the leverage. The consequences will be: 1. Lighter effort. 2. Less master cylinder motion. 3. If it's lengthened too much it may physically hit the floor or snag on your carpet.

There is no consequence regarding springs or damaging the clutch in any way. If anything, there may not be enough clutch travel to fully disengage it.

yep, depending on the shape of the pedal and the shape of the floorpan, the pedal could hit the floor before the clutch is fully disengaged.

well,

i gather if i shape the pedal arm the same as my brake one, all should be ok because the brake pedal doesn't go to the floor even with nothing hooked up to the system. i forgot i'll have to cut my wide pedal pad off the brakes and put the small one on.
