Wow, finally finished building the RRR and after a brief practice run (mainly to set the 2 speed and clutch) i`m in awe of how seriously quick this car is
After reading comments here about the pipe stay i decided to experiment with the pipe stay and using some bits and pieces have one thats fairly rock solid.
For those interested, i used a wire mount from a NTC3 (part #2358). It simply goes into the pipe the same as normal, then its simply a case of using a 3mm bolt, 3 washers, and a nut to mount it through the vacant hole in the top of the radio tray.
Running an RB pipe the wire mount is perfect size and doesnt need any mods.
Hope this helps someone out
