Back to the original question:It will probably surprise you how well your challenger will handle if you just do the basics ie:properly sized swaybar, good but not great aftermarket shocks-(kyb instead of koni), big sway bars on each end. To give a quick example when in highschool I had a 73 'cuda w/440 It had stock 340 torsion bars-factory sway bars and new KYB shocks. That car handled just a little better than my fiance's 96 honda accord, I know this cause I was thrashin' her car on this one particular backroad two weekends ago. So.... just a good common sense approach will get you a pretty good handling car and as soon as the road straightens out lookout-big block mopar coming through
