Description

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.

All bars come zinc chromate plated. I can powder coat matte black over zinc for $30 extra. Any additional colors will be $45-80. We will verify your color & adjust/refund your invoice accordingly.

☆ Dual Mini Hooks:

These welded hooks provide easy access tie-down for dyno or transport on trailer. Dual hooks can welded at any angle, 45*, straight back, or downward. Most commonly is downward. We will verify your specs before fabrication.

☆ Hidden Universal tow strap bracket:

This welded bracket allows for universal tow straps to be bolted on. Tow strap bracket can be placed on driver or passenger side. We will verify your specs before fabrication.

☆ 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 behind license plate). The most popular location is behind the license plate. We will verify your specs before fabrication.

☆ Dual M8 pucks for diffuser support rods:

M8 pucks make it easy to attach rear aero bracket or support rods. M8 pucks are placed on the bar based on your setup. We will verify your specs before fabrication.

Engineering Design Notes:

☆ In order to keep the bar tight to the backside of the bumper cover, we designed the bar with quad bends. This follows the recessed license plate cavity. The bar is tight on the sides and center. No other bar on the market features this design.

☆ Having the bar tight to the license plate also allows us to use the recessed cavity of the bumper to hide M12 tow bung, or M8 pucks to attach rain-light or camera mounts. Simply reinstall your license plate when on the street. See photos in gallery

FAQ

Q1: Why replace the stock rear bar?

A: The two reasons would be for weight reduction & safety. OEM rear beam is one of the first items to rust away since it traps most of the rain, snow, salt. Rust breaks down the welds & material which reduces strength & safety of the beam. Doryoku tubular bar is a direct replacement made of stronger material yet lighter & provides built in provisions for needs of track/enthusiast cars & can be customized further.

Q2: What is the weight savings over stock?

A: 8 lbs (50%) 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.

Q3: Powder coating is free/standard on your front bar, why is it extra on the rear bar?

A: Front bars are "closed tube" so powder can be applied on all surfaces. Rear bar is an "open tube" design which is harder to powder coat inside the tube whereas zinc plating submerges the bar in acid cleaning tank & plating tank to provide more coverage protection. I can apply powder coating directly over zinc for those who want to have rear bars match their front.

Q4: What are the benefits of zinc plating?

A: Zinc plating allows for more comprehensive coverage. Zinc finish is a thin protection barrier which makes it very easy to primer paint or powder coat over. It's also easy to prep for additional welding if you decide to add additional parts to the bar. Powder coating is thicker but less friendly for future modifications such as painting or welding.
