Original door bushing (dove tail/cups) designed by KenAuto in Japan. This is the thickest possible size and most effective door bushing on the market used by thousands on Japanese Roadsters in the circuit. This piece is a replacement for the stock part that the door sits on when closed. By replacing the brittle stock unit, you’ll notice more steering response and less suspension wiggle. This piece will do a great job of stiffening up your Miata. Installs in minutes and creates a noticeable difference in drivability. Some of the JDM shops such as Joyfast & TUCKIN99 had very high praise for the part and use them on all their race cars now! Learn More

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

The Nielex Excellent Tower Bar for NC (2006-2015) has been around for a while and they just released their Version-II. Back when they released the Version1, the angles for cutting the mounting points in stainless steel couldn’t be obtained in 3D (too difficult), but now it’s totally possible. The Version2 now has exceptional rigidity and does not have any bending making it extremely rigid. The stainless steel material also gives it a very exotic/luxury look. The 8-point tower bar reinforces 8 different points and improves torsional rigidity vertically and horizontally. Its trapezoidal form also provides maximum support to the sides and prevents twisting and displacement in the engine bay. Lightweight and easy to bolt on, it can be installed in an hour with no drilling required!Please note that fitting this to a NC2 or NC3 will require removal of sound enhancer tube. Learn More

Nielex made the NC Magical Cross right after testing the 2006 MX-5 at high speed and concluded that it needed improvement for high speed cornering. They did not see NC as evolution from NA and NB and wanted to create the perfect chassis stiffness. As a result, they made a Magical Cross for it and now it’s a very popular product in Japan (most Japanese tuners use this product). It improves steering responsiveness and also helps keep tires to the ground for much more traction during cornering. It also reduces frame twist drastically to have a more stable and neutral car. It basically transforms the car into a real fun go kart that you can enjoy driving in the streets or at the track. It is even more effective when combined with the Pro-Spec Knuckle Arm Support!

Handling upgrade from Nielex for the NC and ND Mazda MX-5 Miata (2005-2016+). The Aisin x Nielex Door Stabilizers are a small upgrade with a big change in the handling of the third and fourth generation Miata.

The door stabilizers are an Aisin product that have been modified by Nielex to fix the NC & ND chassis. They were designed to improve the contact of the door with the body creating both a performance upgrade and a luxury feel. The Aisin Door Stabilizers are easily installed using basic hand tools.
