New Product Release!! JBR 2016+ MX-5 ND/RF Rear Differential Mount

The JBR Rear Differential Mount for the 2016 & up Mazda MX-5 is a CAD designed direct fit OEM replacement. It’s machined out of lightweight yet incredibly strong 6061 billet aluminum. It’s not a weak cast aluminum part like the OEM mount which is prone to bending. 

It comes fitted with 80 durometer bushings to eliminate movement of the rear end in the subframe reducing wheel hop under hard straight line acceleration and when exiting a corner. Installing a JBR mount gets rid of the unwanted slop and flexing which allows for the power to go directly into rotating the tires, instead of flexing the soft rubber of the OEM mount. Giving you better feedback, sharper response and more predictability on throttle input.

  • Designed and manufactured in the USA
  • Weighs only 4lbs 8ozs. 1lb 2ozs more than the OEM
  • Anodized for corrosion resistance 


  • 2016+ Mazda Miata MX-5 ND/RF

The kit includes:

  • 1 Rear Differential Mount
  • Shipping is free in the US & our Hassle Free Lifetime Warranty is included
  • Installation instructions are available in our support section

The JBR Tru-Torsion Front & Rear Sway Bars for the ND Miata significantly reduce body roll and greatly improve the vehicles ability to rotate.

They’re constructed out of 1.125″ diameter .125″ wall 4130 alloy tube for the front and .625” solid 4130 alloy bar for the rear. They’re then powder coated in your choice of red, blue or black for a beautiful look and long lasting corrosion resistance.

Both are 3-way adjustable allowing you to fine tune them for either the street or the track.
Included with each JBR sway bar is our very own sway bar brackets. They’re constructed out of .185″ thick stainless steel and come with 88 durometer bushings and grease fittings. These will never rust and never break. There’s also no need to reinforce the rear mounting points to use the JBR rear sway bar.
