For the Ares, we used a universal Loctar Cable and cable mount. The mount then mounts to the Intake manifold. On the pedal side, we used stock e30 pedal and pedal lever. The lever hit the boosterless brake setup so we had to shorten it. We then added a few holes to be able to accommodate different motors we make test in the future to bring to the market. Remember, the theme with this car is modular.
So after that the loktar cable fits through the stock E30 throttle firewall hole. The firewall hole isnt really a hole though. Its a square. No big deal! We welded a washer to make it round. This made the cable fit perfectly.
Pictures coming soon!
