Flyin' Miata Sway Bar

Supports


I bought a used Flyin' Miata front sway bar for the 00 SE a while back and installed it on the car.   My son got a Racing Beat sway bar for his car, but also bought some sway bar mount supports.  I wanted to add the supports but could not see spending $90 for some bolts, nuts and two pieces of aluminum.  So this is what I came up with.


First I removed one of the sway bar mount bolts.  It is an 8mm x 1.25.  I then measured the distance from the frame to where the bolt head sits when installed.  It is just over 60mm. I then ordered some stainless steel nuts and bolts and some spacers from AllensFasteners.com.  I ordered extra of each since this was an experiment to see what would work.


I ended up using the following:

  1.  (4)  8mm x 60mm x 1.25 stainless steel bolts
  2.  (8)  8mm x 1.25 stainless steel serrated flange nuts
  3. (4)  8mm x 1.25 stainless steel nuts
  4. (2)  5/16" x 1-1/4" chrome spacers
 I cut the 1-1/4" spacers in half, so I could have ordered four 5/8" spacers instead.   I ordered the 5/16" spacers since the hole is perfect size for the 8mm bolt.


This is how I used the parts.

Notice I used a flange nut against the head of the bolt.  This was necessary since the bolts did not have a flange on them.  I used the standard nuts as a lock nut to hold the spacer firmly in place against the frame.


I believe the spacers contacting the frame will be adequate support for the extra pressure exerted by the stiffer sway bar.  They work the same way as the $90 kit that my son got.  


I will keep an eye on them to be sure they work as planned.
