To prove its new APS adjustable shock absorbers and Total Vehicle System suspension provide incredible traction, Hotchkis Sport Suspension founder John Hotchkis Jr. will drive his famous “E-Max” 1970 Challenger T/A through a high-speed vertical loop, today at 3:00pm PDT.

  • John Hotchkis Jr. will attempt a vertical loop in the Hotchkis Sport Suspension 1970 Challenger.
  • If successful, this will be the first “pro-touring” muscle car to complete such a dangerous stunt.
  • Hotchkis’ pro racing credentials include competing at LeMans, Sebring, Daytona and more.

Santa Fe Springs, Calif. (April, 2014) – Hotchkis Sport Suspension has gone above and beyond in the development of its new Hotchkis-Tuned Adjustable Performance Series Shock Absorbers and now they are putting them to the ultimate test of strength, durability, and traction by doing something that no Pro-Touring muscle car has ever done, let alone attempted. Hotchkis will push its famous E-Max Challenger T/A to the limit through a vertical loop five times the height of the car, proving once and for all that Hotchkis parts live up to the brands slogan – designed, built, punished.

Driving E-Max will be Hotchkis President John Hotchkis Jr., who is putting everything on the line to prove that Hotchkis builds the most hardcore muscle car parts available anywhere. “I have complete confidence that our E-Max Challenger will make it through the loop,” said Hotchkis. “Muscle cars have a reputation for being big heavy brutes only good for straight line drag racing. We’ve already proven that we can make them world beaters around corners in countless autocross and road course competitions, so since we’ve already beaten all of our competitors in two dimensions there was only one way left to go – straight up. This vertical loop will prove once again that Hotchkis stands alone.”

Both John and the E-Max Challenger are no strangers to life on the edge. John Hotchkis Jr. has raced professionally in events like the 24 Hours of LeMans, 12 Hours of Sebring, the Daytona 24 and in Trans Am. The E-Max Challenger has seen its fair share of competition as well ever since Hotchkis first introduced the car in 2009. Every year it logs thousands of autocross laps across the country, putting smiles on the faces of every passenger that gets the chance to ride shotgun.
