NC Miata Front Bar

Doryoku Race 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 to ensure the best fit & follows the bumper curvature. The race bar is intended to provide performance benefits & easy to customize options for track car applications (drag /road race).

☆ Splitter mount style gussets
These are dual pattern gussets designed to work with Professional Awesome & Nine Lives Racing universal splitter mount quick release kits. See Tech Link tab. We also offer an Race Bred adapter bracket for their splitter mount kit. See Complimentary Products Tab

 

☆ Extended dual 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. This eliminates the need to go under the car which interferes with splitters, lips. You must make a ¼” vertical slit for hooks to protrude out of the bumper. 

☆ Hidden Universal tow strap bracket

This welded bracket allows for universal tow straps to be bolted on. You will need to make a horizontal slit in the bumper cover for the strap to pull through. This can be placed anywhere on the bar, driver, passenger or center. NOTE: No cutting of bumper required. 

☆ Recessed CNC M12 tow bung

Welded CNC M12 bung allows for thread in style tow strap which is common on modern cars such as S2000, FRS BRZ, BMW, Corvette, Porsche, VW Audi sports cars. We can place this anywhere on the bar (passenger, driver, center). Please specify in the "Special Instructions" 

 

☆ Dual M8 threaded mounting pucks

M8 pucks make it easy to bolt on FMIC, oil coolers, ducting plate, light bar & splitter support rods. M8 pucks are placed on the bar based on your setup. Consulting will be provided before fabrication.

☆ Custom powder coating

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

 

 

Engineering Design Notes:

  

 ☆ Maximum protection

Roll cage spec tube is used to protect everything behind the bar. We also want the maximum distance from the bar to the vitals of the car (engine). Think of a roll cage door bar where the old school design was a straight bar less than inch away from the driver's body compared to a smarter design door bar that kicks out from the B pillar towards the door-skin then curves back into the A pillar giving the driver much more space and protection from an impact. We use this same approach in our bumper bars.  See Eric's video.

☆ Maximum air flow

In force induction application, more room behind the bar allows you to run larger FMIC, placing FMIC further away from the radiator core provides more  air flow/speed as it passes through FMIC rather than having air flow slow down due to having FMIC & radiator stacked up behind one another.

 

☆  Maximum structural rigidity

A strong tubular bumper bar adds chassis rigidity to the radiator core support. The weakest link of the front end is the radiator core support. We added gussets to increase strength when the bar is used as tie-down & M6 weld nut provision for additional bracket to mount OEM undertray
