Grandpa Mayhem @ The 24 Hours of LeMons

After watching David Freiburger and Mike Finnegan take the Rotsun to the 24 Hours of LeMons on a 2015 Roadkill episode , I hatched a plan with 3 friends to build a car and compete, Rot Rocket Racing team was born.

The 24 Hours of LeMons is a budget racing series for cars under $500. You build your car to race safety standards and apply a theme. We decided to spoof Roadkill's 1968 Dodge Challenger "The General Mayhem".

We were featured in the Lemons race recap video after winning an award at the event:

Here's a walkaround of "Grandpa Mayhem" in the Gingerman Raceway paddock - our 1993 Buick Park Avenue Ultra race car.


The night before the race, we each took a lap around the paddock to get a feel for the seat, controls, belts, hans device for the first time.

Here is some fairly boring in-car, on-track footage from the GoPro mounted to the rollcage:


Quick rundown on the car:

  • We bought the car for $200, transmission started acting up
  • Pulled the engine, installed a fresh craigslist motor
  • Stripped the luxurious interior and all glass but windshield
  • Fabricated full race-spec roll cage
  • Installed aluminum race seat and harnesses
  • Cut springs on all four corners
  • Drilled and slotted brake rotors, performance pads
  • Added larger wheels with some sponsored Chinese tires
  • Removed exhaust, added a side pipe
  • Smaller pulley on the supercharger to increase boost
  • Mesh grill, LED headlights
  • Charger louvers on doors
  • Mopar-style hood scoop supported at center with stack of nuts
