I called Jeff at Hendrick Dodge (got the info from the buy/sell forum) and discussed suspension options available from Dodge. He explained that there are actually 4 levels of suspension components available for our cars...touring, sport touring, performance and sport, with the sport suspension being the best handling but definitely very stiff. He said the RT's came stock with the performance setup. He was very helpful throughout the conversation.
So I ordered the sport setup...front and rear struts (he was unsure of manufacturer), front and rear strut mounts, front strut bearings, sway bar bushings, upper and lower sub frame bushings, outer tie rod bushing kit and rack & pinion bushing kit. While I do not think it would be fair to divuldge prices without his permission, I can safely say the ENTIRE package was $250 less than the estimate from my local Dodge dealer to replace ONLY the front struts and the sway bar bushings (no mounts or anything else)!
I expect delivery late next week and hope to have this plus the H&R springs installed the following weekend. I will provide info on the results after completion.
I may also consider new tires...right now I am running Michelin Pilot Sport A/S 225-55/15. Perhaps a wider tire with a lower profile will be next!
