Functional Splitter - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

CamaroEMC · 05-21-2019, 05:11 PM

I have searched this forum on a number of occasions and have yet to find a definitive answer.

What are you track oriented folk doing to install a functional splitter to the front of an SS Camaro. I am not talking about fastening a "splitter" to the bumper so that at track speeds it will pull the bumper down, but rather how do you accomplish securing a splitter to the frame?
Thinking like an aftermarket option that can use brackets like a Z/28 or rods that are attached to something solid behind the bumper.

Waddya think? Pics are appreciated if applicable.

My application would be a 2010 Camaro 2SS/RS.

TIA

It's tough to just buy a functional splitter. The biggest issue is the bottom of the front bumper angle. The design is for curb approach, so you have a 4-6* upward angle from parallel. I tried to create a parallel splitter and was somewhat successful. The gap from the factory front "lip" to parallel was 1.5" in the center. The rods are mounted to brackets bolted to the front bumper reinforcement. This way it would not rip off the bumper should I have hit something.
The Z/28 does have a more parallel lower edge but it still peaks towards center at an angle. I plan to switch out to one of those as mine splitter is pretty much wasted from multiple tries to mount something solid.

What did you make your splitter out of?

thanks

It's Tegris and actually a NASCAR COT left over. They were available cheap a few years ago. This one was from Roush and unused. Looks like carbon fiber but stronger and heavier.

Wanted to reinforce why "basic splitters" are still "functional" (depending on your definition of significant) over a factory front end, but even more why extending the splitter back into the engine bay has significant benefit.

I didn't do any of this, but there are plenty of textbooks out there online for less than 20 bucks. This is from "Competition Car Aerodynamics: McBeath"

The takeaway here is that the splitter provides a place for the high pressure of the front of the car a place to "push down" and creates local pressure gradient. As long as there is an element there, they are significant so long as they are of sufficient size.

The other takeaway is that for a minor drag penalty you can increase the pressure gradient further by extending the splitter back to feed a floor.

Depending on your situation a small amount of up angle on the splitter may provide beneficial if you're feeding a flat floor/non aesthetic diffuser as it helps establish the throat, but most aren't.

I've been studying this fairly heavily. One day I'll reveal the #aeromaro.

Let's not overlook the need for aerodynamic balance here.

An effective splitter needs effective rear aero treatment as well, else you could end up "aero-loose" as speeds rise (front stays stuck down better than the rear).
