We were at Auto-Plus Raceway yesterday with our 2009 Challenger, and got some great results using Energy Suspension's new Hyper-Flex performance polyurethane suspension bushings.

How much do polyurethane suspension bushings really help? If you have a late-model Mopar, replacing the soft factory rubber suspension bushings with Energy Suspension's poly units can make a big difference. To test this, we took our '09 Challenger R/T to the road course at Auto-Plus Raceway in Gainesville, Florida.

Testing the car before installing the new bushings, we acheived lap times of 1:16.5 and 1:16.6 seconds. After installing the Energy Suspension poly suspension bushings in bot the front and rear, the car felt much more connected to the road, and more responsive when accelerating from the corners. These improvements really showed in our lap times as we improved by more than two seconds to 1:14.1 and 1:13.9 seconds on our best two laps. This was accomplished with the stock tires on our car and we're sure a good sticky set of tires would further enhance our new suspension components.

Look for all the details on this installation and our results in future issues of Mopar Muscle and Mopar Now, and be sure to watch the videos of our installation and testing on
