LeeSpeed Racing Design have introduced a new generation of 84 pitch spur gears and titanium pinions, available for any EP touring cars. The claimed benefit of 84 pitch is that it is quiet, improves acceleration timing and braking consistency due to more engagement of teeth, which translates to better and faster lap times. For the very same reason, it also will provide constant feedback to drivers throttle response due to a more refined gear ratio. They are available in a range of 118T up to 157T for spur gear and 30T up to 60T for titanium pinion while suitable for stock to modified, non-turbo to turbo.
