RCR Adjustable Pedal Assembly
Chuck Schmidt
The RCR comes with a sturdy floor mounted pedal box. A couple of issues were addressed including making them adjustable and providing adequate clearance for the master cylinders.
The pedals are stainless steel, so a bit of time was spent giving them a nice shine with a Scotch Brite pad. The base, which was plain steel, was painted semi gloss engine black which perfectly matches the powder coated chassis.
Upon assembling the pedals a significant amount of lateral play was noted in the brake and gas pedal. A thin piece of brass was cut to size and wrapped around the pivot bolt, eliminating much of the extra slack. When the bolts were tightened the excess slack was gone and all three pedals moved smoothly with minimal side play.
We tapped a hole behind the gas pedal and added a 1 ¼" screw to serve as an adjustable stop screw. The gas pedal has a nice little pad welded on the back side.
The two drivers for our car have a four inch height difference; a possible dilemma in a car intended to fit a single driver. To give us a bit of flexibility, an adjustable pedal mount was sought. A unit from CNC, Inc., San Diego, California was selected. www.cncbrakes.com.
It raises the pedal assembly only a quarter of an inch. The base plate is made from a nice machined piece of aluminum. Centering it under the pedal assembly, we were able to find enough area to drill the mounting holes for the four slide bolts. To adjust the pedals one pulls it backwards and then replaces it in a different set of mounting holes. Simple, neat, and functional.
The RCR kit came with three Wilwood master cylinders: two are one inch diameter and one is 7/8" diameter. The smaller is intended to be for the clutch and the two one inch cylinders are for the brakes. We replaced the supplied clutch master cylinder with a different style.
Getting enough forward travel for a tall driver while assuring there was enough space for a size 11 foot to rest on the gas pedal was an issue. The supplied clutch master cylinder extends far enough forward that it interferes with the suspension bracket housing when the pedals are pushed to a forward position. Wilwood makes a smaller cylinder, "Compact Remote Master Cylinder", part 260-7577, which has almost the same fluid volume as the one supplied with the kit. It is significantly shorter in overall length, giving more travel distance on the adjustable bracket. With this shorter master cylinder, the pedal assembly can be adjusted so that a driver well over six feet tall with big feet will fit.
Getting the supplied hydraulic hoses to fit was a challenge, given the adjustable pedals and the need to push the pedal assembly forward to accommodate a tall driver. Although the straight hoses will work we decided to purchase three 16" hoses with a 90 degree fitting on one end. (Earls EAR-630117 16, from Summit). This resulted in a better fit on the clutch as well as the brake master cylinders and will minimize twisting when the pedals are adjusted fore and aft.
The pedal assembly was installed in our left had drive car with the forward right corner of the CNC base plate 6 ½ inches from the center tunnel and 6 ½ inches from the firewall. This location provided enough room for a large shoe to fit on the gas pedal and enough clearance to move the assembly fore and aft.
