Thoughts on pedal boxes

[Motorcitydak]

I plan on using a triple master cylinder racing pedal box/assembly with an adjustable balance bar, remote cable balance bar adjuster and built in hydraulic clutch. Not sure if I will get one with a throttle pedal I can just use a DBW pedal. What I am curious about is if I should get something that mounts and hinges from the floor or the firewall. I have never driven a car with pedals on the floor so I am not sure if I will like them hinged like that. Also unsure if I have the room for them since there is an angle up on the floor where it comes to the firewall. If necessary I could modify the floor since the engine should not be there. There will not be much space taken up by the steering column so I should be able to mount the pedals on the firewall. Looking for feedback from someone who has used either. Also I just got my seats for the car and the brackets should be in soon so I can place those then figure out there the pedals will go

Wasn't sure if this thread belongs in disk brakes since its really not about that. Also these are some examples of the pedals I have been looking at. I want something around the 6:1 ratio. I want the pedals nice and close so I can heel-toe this beast when its done!

Im leaning towards one of these with remote reservoir master cylinders, not sure on what bore to use yet. Both have a 6.25 ratio which should make up for my using manual brakes but Ill still have a nice firm pedal. Also with noting that the pedal I use is hinged from the firewall. It may be possible to run it upside down tho

The Wilwood pedals are 11.89 inches from pivot to bottom of the foot pad, Tilton is 10.4 so the Wilwood would give more force with less input

Steve,
Most floor mount pedal assemblies have about a 5:1 ratio. Even though they look similar to the swing mount, the foot pad angle is different on most of the pedal arms. The problem with running a higher ratio pedal arm on a floor mount is the distance the foot pad ends up above the floor. Most drivers don't have feet that big! Your thoughts on the problems with the floor pan are right on the money. Think about exhaust heat. Also keep in mind that the footwell area was never designed to take the force of brake pedal leverage, so you will need to add some serious bracing to eliminate flex.

If you are designing the car primarily for track use, the lower pedal ratio will give you better control. We don't really build race car brakes for panic stops... The more input force you have to use, the better brake modulation you will get in return
