NC Miata Rear Bar

Doryoku Track bar’s philosophy of use & design

We designed this to be the best value bar on the market when it comes to weight, construction, design, add on options, price and total value. All bars are designed by scanning the OEM bumper bar/foam/support so that we can ensure the best fit and follow the existing shape. The track bar is intended to provide many performance benefits for track car applications (drag /road race) while allowing the user to customize the bar as they grow in the sport.

Custom Options

☆ Dual coating zinc + matte black powder

For those who want additional protection or just like a stealth color, powder coating matte black is durable & cost effective. 

 

☆ Custom powder coating

I stock over 35 popular colors. Powder finishes are available in wrinkle, matte & gloss. Please note in "Special Instructions" what color you would like.

 

☆ Extended dual drop tow hooks

These welded hooks can be used for easy access tie-down for transport. This eliminates the need to go under the car which interferes with splitters, lips. Consulting will be provided before fab.

 

☆ Hidden Universal tow strap bracket

This welded bracket allows for universal tow straps to be bolted on. The Tow strap bracket can be placed on the driver or passenger side. Consulting will be provided before fab.

 

☆ Dual Mini-hooks 

1/4" thick steel dual hooks are an excellent choice for easy/fast tie-down for transport and dyno. Hooks can be placed down and require a half cut bumper. Hooks can be faced outward at any angle but require a vertical slit in the bumper. Consulting will be provided before fab.

 

☆ Jackpoint 

Jackpoint will extend 1/4" beyond the bumper tray 

The Miata diff is 40" away from the bumper. Most floor jacks are going to have 20-24" of reach (jack pad to lower handle). Super-long floor jacks will have 30-34" of reach but are $500 & weigh over +80lbs. Miata owners must get down to floor level in order to see and line up jack to the diff to jack pad, then you still have to go through the motion of doing "micro-pumps" (because jack handle is hitting bumper) before the car is high enough to get any decent travel from the jack handle. This jackpoint tube eliminates those annoyances while keeping the visual footprint & bumper trimming minimal.
