Description

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).

Customize options

☆ 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. The dual hooks also have an M8 hole which are used for mounting splitter support rods. NOTE: very minimal trimming to the bumper is required. Trimming is not visible from the outside.

☆ 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. Consulting will be provided before fab.

☆ 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). Consulting will be provided before fab.

☆ Dual M8 threaded mounting pucks

M8 pucks make it easy to bolt on FMIC, oil coolers, ducting plate, light bar & splitter support rods. We offer 1" and 3" long M8 pucks. See gallery. 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. The bar allows for bump drafting / W2W contact. Our bars are proven by W2W racers in Gridlife GLTC, NASA, SCCA, Champcar Endurance Series. See Eric's video.

☆ Maximum air flow

In force induction application, more room behind bar allows you to run larger FMIC, place FMIC further away from 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. It comprises thin stamp steel with huge opening compared to firewall that is closed off, fender frames that are much thicker steel.

FAQ

Q1: How much weight is saved over stock?

A: 12lbs weight savings

It's not so much about how much weight is removed, what's more important in any track car is "where" the weight is removed. Anytime you can remove weight from areas beyond the wheel it improves the car's natural balance & gives you the control to strategically add weight back in where it's most beneficial for your setup or race series. Check out this video from Ben as he talks about weight reduction & distribution.

Q2: How much space is gained over the stock bar?

9” on the small ends and 11” in the center. Many customers can easily fit a tuck-radiator and +6” thick FMIC.

Q3: Will the bumper still fit like stock?

A: It will fit better than stock. We discovered the reason why OEM bumper sags on Preludes is because there is no adjustment to the OEM bar to move it up or down. The bumper "skin" is bolted to the bar which makes the bumper skin non adjustable. Secondly the OEM bar does have a metal bracket which bolts to the plastic grill, but that grill is mounted to plastic headlight housings, with both pieces being plastic having the grill attached to the bumper is pointless as the grill only needs to attach to the headlight housing. With the lack of a firm place for the bumper to "hang" , we designed our bar to have 2 metal tabs for the bumper skin to mount on. Rather than a hanging bumper tension, we created a push up tension.
