DaveFAB jacking bar install for the NB!
This guide will show you how to install a DaveFAB jacking bar to your NB MX5! For the NA's, the unit simply replaces the stock towing eyes and bolts as normal. However, on the NB you have to drill your own holes and use nuts and washers to mount the bar. Not a hard install but can be daunting if you've never seen it done before!
Firstly, mock up the jacking bar against the chassis legs and ensure there is nothing getting in the way of it sitting flush. Then mark the holes with a marker so you know where to drill!
The jacking bar appears to want to share some of the crash bar bolts. However, they done line up and all I can think is that they are there for extra fasteners if need be.
Once the hole positions are marked, center punch then drill to accommodate the M10 bolts. I drilled mine to 10.6mm to allow for 'wiggle room'.
While you are under here, it would be a good idea to blast some underseal around the boot floor and rear chassis legs.
I found it easiest to do the top bolts first. Use blue-tac to hold the nuts and washers together, and electrical tape in the jaws of a spanner to hold the nut tight. This will mean you can put the spanner up the chassis leg and thread the bolt into it without the hardware falling all over the shop.
After you fiddle all 4 bolts in, tighten it up and admire your hard work, treat yourself to a beer!
In my opinion, the DaveFAB jacking bar (or any jacking bar) is an essential modification to be made, especially if you plan on lowering the car! I find it much easier to use than jacking off the differential, and it sits much higher than the diff so you can fit normal jacks under the car, not just low profile ones!
