Splitter Support Rod Integration

Splitter Rod Mounting Options

The versatility of Doryoku bumper bars brings so much value and purpose to the cars front end. Outside of the many benefits you acquire with the bar, it also serves as a fundamental component in the aero department. There are a few ways that splitters can be integrated into the bar build.

Option 1: Tow Hooks

Doryoku offers a custom optional tow hook that doubles as a secure mounting point for splitter rods. The tow hooks are welded directly to the bumper bar and are predrilled with M8 size through-holes to make splitter rod mounting easy. With the stamp of approval from Mike Lewin at Professional Awesome, this tow hook was developed specifically to accept Professional Awesome splitter support rods. PA clevis-type mounts use M8x1.25 thread which fits perfectly through the tow hooks. 

With this option, you won't have to cut the bumper to clear the support rods since the tow hook design already protrudes through the bumper. You get plenty of room to dial in the rod angle to your liking. However, you do sacrifice the ability to place the support rods in a location of your choosing due to the required fixed position of the tow hooks. 

Option 2: Mounting Pucks

Doryoku also offers a custom option that can be utilized for splitter rod mounting. Mounting pucks are short sections of 1018 mild steel round bar with a threaded hole in the center. They're designed to be welded onto the bumper bars as a mounting solution for various needs and in this case, for splitter rods!

You have more freedom on where to mount the splitter rods since the mounting pucks are radiused and can be positioned anywhere on the bar. However, you will have to cut or trim your bumper to clear the pucks and potentially the splitter rods themselves depending on where the pucks are placed. With the pucks, you'll need to utilize a stud in order for it to accept the "female" end of the PA splitter support rod clevis. 

Additional Info

Professional Awesome splitter rods have been mounted this way in the past with various applications. Just to be sure, Mike was kind enough to run a Finite Element Analysis (FEA) to confirm this would be acceptable. One benefit of the fiber rods is that they can absorb some mild contact to help prevent damage to the splitter or other components in the system. Worse case scenario, the fiber rods would bend or break before the clevis, bolt, or stud would shear.
