Our ACR customers are getting ready for the club-racing season and we have prepared several for track use. We were really surprised when we tested the first ACR’s in 2008 and they were only 3 seconds off our Competition Coupes. With some minor changes we are going to see how much faster they can really go.
We have been doing the basic track prep and safety changes to the cars. We start with changes to the Aero, ride height and alignment, steering rack bushings are changed to the solid type, sway bar bushings upgraded and the shock compression and rebound adjusted. We install a welded in rollbar, fire extinguisher and safety belts. Driveline upgrades are minor, we change the transmission mount and shifter (short throw) and on some cars we change the motor mounts (If they do not mind the vibration). For shorter tracks we change to a 3.33 ratio and add a Quaife for better traction. The brakes are great, but better brake lines and pads make them world class.
For power adders we have been using the Belanger headers, high flow air filter and Mopar PCM (with 93 fuel), good for 60hp!
We will be out at button Willow next weekend for the NARA Event soon and see how these cars do.
