Hotchkis had thier E-max Challenger with all the TVS suspension stuff I have at the Motor State Challange this year in Detroit. The other cars were DSE Camaro, Steilow's latest six $ figure Camaro creation, etc, etc, $$$, $$$... Full custom stuff, beyond kits you can buy.
The Hotchkis E-max Challenger was top 2nd in Road Course and 1st in Autocross and the road course out of 90 participants. The Challenger runs high 13 sec 1/4 miles times. The other cars that were faster had 500+ horsepower motors, pretty exotic stuff. The E-max Challenger spotted the 1 car that beat it at least 200 horsepower.
