RX-8 to MX-5 / Miata NC Knuckle Conversion

RX-8 to MX-5 NC rear knuckle conversion parts. It's well known that the MX-5 bearings and hub flanges are prone to collapse through hard driving. The RX-8 rear knuckle conversion is the best value modification to remedy this MX-5 weakness.

The RX-8 uses a larger bearing housing with larger bearings and a thicker flange, and is much stronger in design over the MX-5 units. This modification requires a Frankenstein pair of shafts which uses a RX-8 outer joint, only found on the automatics, which are not available in the UK. I bulk import the correct components from Japan for the modification and supply all of the components to allow a direct fit of the RX-8 knuckles onto your MX-5. Providing peace of mind when you're hitting the curbs going for a PB!

What's included:

• 2 x RX-8 / MX-5 pre-used driveshaft Frankenstein modification - imported from Japan
• 2 x RX-8 pre-used rear knuckles - imported from Japan
• 2 x MX-5 ABS spacer adapter
• 2 x MX-5 new ABS Sensors (non-genuine)
• 2 x RX-8 new rear wheel bearings (genuine SKF Made in Japan) 
• 2 x RX-8 pre-used wheel hub and new Genuine Mazda wheel studs (extended studs available as an option)
• 2 x New genuine Mazda toe pinch bolt with nut
• 2 x Diff bungs (to limit the loss of fluid and ingress of dirt as you carry out the conversion)

All parts are checked for damage, stripped of all components, before being vapour blasted and rebuilt.  It's worth making note that we don't just import the drive shafts, but we also import the knuckles from Japan.  We have found UK rear knuckles experience excessive corrosion due to the salt used on our winter roads.  Japanese knuckles, once cleaned up look almost new with very little, if any corrosion present.

NOTE: The standard rubber trailing arm bush is removed (and not reinstalled) as part of the strip-down process and shipped ready for your own bush installation. We can supply spherical pillowball or poly bush options, which are available upon request. We need to be aware of this prior to paint and reassembly.
