    Idk if anyone has had this issue. The rear suspension constantly feels like it's swaying right to left and gets worse the faster you go or if you change lanes at 75mph highway speeds. It becomes rather violent and scary at higher speeds. You can barely feel it cruising but it's very pronounced under hard acceleration. No whine from rear but I did note that the tires are wearing a little odd in the rear. Doesn't seem to matter if suspension is in street or sport or track mode. Anyone seen or heard of this?

    Check tire pressure might be too high or low set to what's on the sticker COLD. Charger is 32 all around don't know Challengers.

    Take it in and have it checked, are you using stock tires or did you change them?

    Or are you spinning the tires too much at too high of a speed?

    Tire pressure is good, between 34-35 when fully warmed up (Texas heat...lol)

    Definitely going to take it in. The tires are Pirelli Pzero 305/35/20 in rear but it did it with original tires as well. Only 1700 miles on the odo. Nothing visibly obvious but by the wear pattern on tires that are almost fried in the rear with only 500 miles on them looks and feels like scrubbing you get with messed up toe adjustments in a front suspension. Hard to say without getting it on an alignment machine.

    If the rear align is out and not from outside influence make them buy tires.

    zigga It ended up being the pesky Pirelli 305s on the stock 20x9.5 rims. The sidewall was just way to hard and they tracked bad. A set of aftermarket 20 x 10 rims with nitto 555rs in 305/35 and now I'm getting easy averages 0-60 of 3.6 and 1/4 of 11.4 without breaking a sweat on the street :)
