I keep seeing the 2011 challengers/chargers have better steering and suspension, but what exactly was changed on the car to achieve this.

Also, do the srt8s have these improvements as well?

The steering gear ratio is revised in all Challengers to a faster ratio
16.1:1 ('08-'10) to 14.4:1 ('11). This increases the steering feel and turn-in.

The rack & pinion mounting is also revised for more positive steering feel.

The front suspension was given more negative camber and the front suspension mounting points were changed to provide more handing feel and improve wheel camber during cornering. There are revised suspension bushings in the '11 design as well.

The rear suspension has negative camber - on R/T and SE SS Group, they gain a larger 20mm rear swaybar. The rear suspension bushings are a stiffer rate for '11 models as well. [The SRT8 392 still utilizes the 16mm rear bar].

The shock rates front and rear underwent revisions across the various trims as well.

Super Track Pack option (R/T only) has revisions to the shock rates over the 'standard' R/T Performance level suspension spec.

Thanks. So pretty much every improvement was carried over to the srt aside from the bigger sways. Any reason why they were left off?

I know the SRT models have tighter shock valving and higher rate springs - didn't know if the engineers felt that stiffer sway bars might compromise the ride quality?

The R/T 'standard' springs and shocks aren't firm as the SRT versions.

Sorry for a bit of a hi jack....

Which of the above revisions are possible with the mopar suspension upgrade for the pre '11s (the one that is like $500 bucks and is based on the '11 suspension)

What im curious about is how much of those improvements do we get from that mopar suspension upgrade?

You can get a complete SRT-8 suspension upgrade from Mopar under 500.00........................goes right on a R/T! Add the better bushings front and rear from the '11 and you will be golden!
