BB6 Prelude Front Bar

Doryoku Race Bar’s philosophy of use

 

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 race 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

 

☆ 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.

 

☆ 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 note in "Special Instructions" what color you would like.

 

 

☆ 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. Powder finish are available in wrinkle, matte & gloss. If you select "Powder Coat - Custom", please note a few colors you would like and we will reach out to you to confirm & provide color samples.   

 

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 the bar allows you to run larger FMIC, place 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. It comprises thin stamp steel with huge opening compared to firewall that is closed off, fender frames that are much thicker steel. See crash test results from our Enduro TSX.
