There is a lot of room for pedals in there especially if you drop the floor 2". Yikes there is alot BUT if this is a race car you want to have access, easy access to them at the track.
The stock location is actually not bad for that at all. You can stand up and service them in the front trunk the way they are now.
If you move them to the floor assembly, which can be done, you could come up with some type of a trap door assembly BUT you most likely will be on your back, under the car to work on them.
Look at the Cobra setup. Maybe you could adapt that and have it swing down to service it, using -3 aeroquip 8807 teflon lined hoses instead of tube so it could be flexable?
