You all have seen the custom speed hole plates on our ZZP Drag Sonic and Al's "Honeybadger" Ion redline. After being asked many times to sell these parts, we present our ZZP Speed Hole Plate, designed for the Sonic RS/LTZ Hatchback rear bumper, but can be universally fitted to most vehicles. Also makes for a great garage wall art piece. 

"Speed Holes" are used in many drag car, road course, and hypermiling applications. As air flows underneath the car it gets swept up after the rear tires. On many of our street cars, the problem comes when a portion of that air gets forced up into the rear bumper, and thus trapping it while creating a parachute affect. Speed holes allow escape holes for the trapped air, while correcting some OEM vehicle rear aero issues as well. While it may not be much, this will slow your car down marginally. Every bit counts when you are fighting down that last second on your pass or lap time. 

We improved upon the design our drag cars have by making the hardware holes .125" for rivets. This will make installation easier and save weight, so be sure to have a decent rivet tool and that hardware. If you would prefer to nut & bolt it you can drill out the holes to your liking instead. 

Comes in raw stainless steel finish that has lasted 2 years on our Drag sonic that lives outside with no issues or degrading of the finish.

Bumper must be cut underneath to provide air access to the large holes and ZZP cut out.

Plate is 42" wide by 4" tall

Does not include hardware.
