Differential Swaps
The MX5 NC has a small case differential housing a 7" pinion and the NC MX5 was only available with a limited number of ratios. For many short course racing such as hill climbs, sprints and circuit racing the standard diff ratios might be too long, and you might favour quicker acceleration over maximum top speed.
We can offer the components to swap your differential from the standard MX5 unit to the larger and stronger 8" pinion RX8 diff, which have shorter ratios available.
