3 days of racing with BMWCCA, thanks to the Tarheel club!
The size of the rear control arm rod ends is such that there is NO way to put a wrench on the interior jam nut. The rod end fits into the subframe with no space for a wrench. Terrible.
Resolved by hacking, cutting is too elegant a term, metal from the control arm mount. Next time, will know to look for a control arm with a smaller rod end.
Not sure where to place the fire bottle (it’s tiny!), battery and cool shirt system(yet tbd).
Thinking the cooler will go where the passenger seat mounts.
Battery and fire bottle have wires & tubing to run. Along the sill would be cleaner than runs along the tunnel. Some pictures for consideration.
