Nielex is always trying to find ways to improve Mazda’s Roadsters. They came up with this Brake Master Cylinder Stopper that will fit the 1.5L and 2.0L ND MX-5 (2016+) as well as the Fiat Abarth 124 Spider. The bulkhead that attaches the master cylinder from the brake pedal is quite thin and this piece solves the brake pedal firmness issue. It’ll give the pedal a more linear feeling versus OEM. It’s made of 2 parts for ease of installation and design coolness! Nielex Brake Master Cylinder Stopper should be ordered at REV9 Autosport https://rev9autosport.com/nielex-brake-master-cylinder-stopper.html as they provide the best service and speed we've seen so far!
