This seems to be a popular mod amongst the MR2 community but I wanted to put my own spin on things. Here are the OEM MR2 Pedals (This is the best pic I have):
The problem with leaving the plastic Deadpedal is that, to me, it just does not look right. So, I decided to compromise between the two. Take the OEM Deadpedal and remove the tread.
Copy the image to the Celica Deadpedal. I picked the area that would not get any holes as I wanted a smooth pedal. I can always add them later if I want.
Now I get to tear the crap out of the Celica Deadpedal housing. I cut 2 tread pieces out, sand them from the back to get rid of the mold gussets, and then glued into place with some 5 minute epoxy.
All in all it was pretty easy. It took me about 3 hours worth of work to get it all buttoned up. I will post up some pics in the car once I get a chance.
