Ok, I have had enough of the gas and gaz pedals coming off because of that dumb nub design from bmw. Time to do the conversion to a hinge.
Since this is a track and street car that has carpet, I could not just bolt it to the floor. Have to preserve the concept of two things sticking up from the floor through the existing holes in the carpet.
Short version of the process I am following is..
-cut off existing nubs and nub holder
-install two bolts through the floor and secure then top and bottom with alum bar and lock nut
-attach a hinge to the pedal
-screw nut onto bolts about half way down. This holds hinge above the carpet
-install hinge and pedal on bolts
-add another nut on top.
Various parts. Note the good set of nubs I cut out of Barney. Use those for reference and measurement
Pulled existing Gaz pedal off
The different pedals. Note for stock pedal use, must cut off the nub cups on bottom. (center pedal)
dimension of the pedal are
3in wide at bottom
2.25iin wide at top
off with their heads!
nub support removed
These things suck…
Here are the pieces of alum bar stock I am using to sandwich the floor pan. replacement for using washers.
Ran out and bought some parts. These are all the nuts and bolts needed.
Here is the roller bearing on the accel rod that rolls on back of aluminum pedal I made.
here is the info on the bearing for the accel rod. credit for research on finding this goes to Lee at Massive.
Drilled some holes in floor that lined up with hinge and aluminum bar holes
Attached hinge to gas pedal
Put bolts and plate on bottom. Goobed on some black RTV to seal it up under the plate
Plate and nuts on top.
Now the hinge support nuts go on. You can set these at the height you want the bottom of pedal to be. Put washer on top of nut, put hinge on, put another washer, then another nut.
With test fit done, remove pedal and put carpet back in
Rock solid. No way it is ever going to come off again while matching revs going into a turn on track. Whooo hoooo!
The mod is invisible unless you look behind the pedal. Same mod can be done to a stock pedal.
