Summit Racing Equipment already stocks lots of new parts for the LX Mopars, and sent us a lowering and sport suspension kit from Eibach. This kit not only improved the looks of our Challenger by lowering the car about an inch and a half, but also improved the car's handling characteristics dramatically. The Eibach suspension kit comes with new struts with more aggressive valving, and larger diameter sway bars as well. Our friends at Inline Performance Specialists made short work of the suspension upgrades, which required the removal of the entire rear subframe in order to install the rear sway bar. The Eibach suspension upgrades, along with a bumpsteer kit and adjustable sway bar end links from Razor's Edge Motorsports, made a noticeable difference in the handling of our car, without negatively affecting ride quality. The car really turns heads now as well, with the visual upgrades and lower stance.

Next we moved to our car's NAG1 automatic transmission, ordering an upgraded transmission and converter package from Gearstar Performance. We've obviously got plans for a more powerful engine in our car's future and wanted to be sure the transmission was up to the task. Gearstar Performance offers several levels of modification for the NAG1, upgrading our transmission not only to handle the abuse our supercharged stock Hemi will give it, but also readying our car for even more power in case we build a bigger Hemi for our Challenger.

So far, we're happy with our new Dodge and are enjoying the looks and performance of the upgrades we've performed so far. It's great to be able to jump in a new Dodge car and do a burnout with the rear wheels, which until lately wasn't possible. But with our car driving and performing better than it did new, we have to consider what to do next. Should we upgrade the independent rear suspension with new axle shafts and a new differential? What about upgrading our car's disc brakes? We're also considering lightening our car up as well as improving safety and stiffening the suspension with shock tower braces and maybe even a rollbar before building a new engine.
