Product made by Nielex. The original front knuckles lack the sufficient hardness of the lengthwise direction in the structure. The drivers feel that the strength of the handling is not good enough especially when they drive in cornering at the high-speed because the deflection of the knuckles is very obvious. Nielex thought up the Front Knuckle Arm Support in order to solve these problems. While we were developing this new product, we were able to get advices from Mr. Oda who used to work for Mazda for a long time and were in charge of the development of chassis and suspension of Mazda's sports cars. Once the driver installs this product, I can say that everybody can feel the wonderful effect. It can be felt even during the low-speed drive. The most impressive effect can be felt when a car runs at over 140km/h, and the driver can feel that the handling gets more stable. NA with ABS : you will need to re-route the cable of the ABS sensor. Learn More
