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.
Big tires and low gears

Been following the articles on the late model challenger - Great job so far! There is a lot of interest in dropping weight from the challenger to help its track times. If you could do something about removing weight, without removing the creature comforts, would be welcome. There must be some aftermarket support for these cars now. I know the 6.1L SRT's have the option of using an aluminum block that sheds considerable weight from the front ... perhaps there are other weight-loss options out there for your 5.7L build.
Stay with the 5.7, would like to see some handling test with mods. Needs wider wheels and tires. How about a 1/4 mile run on drag tires. I painted the lower black area on my 09 challenger looks like it should of from the factory, makes it look like it's on the ground. Can not put lower gears with stock 1st gear in trans. Just a note I have over 93,000 happy miles on my 09 challenger. With a few mods I ran 13.68. Yes I still own and drive my 1969 white Javelin.
I think changing the 3.06 gear ratio to 3.73 along with a set of slicks would easily put this car in the 12 second range.
i like to see you reinforce the internals and crank the boost. possibly a fuel system upgrade would be needed.on the appearance side, i'd really like to see someone downplay the extreme body thickness. remove the plastic panels around the bottom. paint the front/rear valence panels flat black (under the "bumper"). continue the flat black beltline between the wheels, ie. which would include the doors. this would help make the car look thin. instead of a retro bumper kit, take the oem bumpers and wrap them in a mirror like graphic. reflectech makes the perfect material for this, but a pro is required to wrap it around corners without wrinkles. try to lower it a little more.
We didn't dyno the Shaker, because with the Procharger we couldn't duct it directly to the air inlet filter. In a normally aspirated car we'd expect a gain from the fresh air.
Check RPM for your roll bar, we'll be doing an installation in an upcoming article. Don't bother with a two point, not sure anyone makes one and two points won't do anything.Good idea on the 5.7 we'll likely starting off building a 5.7 with forged internals, heads, and cam.
Don't do a motor swap, just totally build thatt 5.7L. And more of us have them. Any ideas i can get that will work for my ram the better.
Did I miss the long tube vs shorty headers? Were can I get a 2 point roll bar for my 2010 Challenger? How much HP did the Shaker hood add?
look i love this car i found it on the interent when it got leaked out. Looks good but chrysler is doing the the same game here lets make it 470 hp i mean come ON! make it like 530hp for the SRT8 pick up the game and play it right. im tired of hereing chevy and ford that are ligther and faster than the Challenger!
