The rims are Mille Miglia MM11-2 in 18 x 8. The tires are Dunlop SP SPORT 9000 in 245/45/zr18. Got the rims from Tire Rack (www.tirerack.com), got the tires from Discount Tire. The rims were ONLY $179 (which is great for 18's) and the tires were $247 each. Would have got both tires and wheels from Tire Rack but they don't have 90 days same as cash like Discount Tire did. The tires would have been cheaper at Tire Rack (about $28 each). I already have buyers lined up for the old wheels and tires which are in great shape (only 10500 miles).
Mopar Head, my R/T is a 2000. The spoiler came from www.thespoilerfactory.com for $217 including the paint and shipping. It looks just like the factory spoiler (it probably is for all I know). This same place also sells the wood dash kits also. They have a really cool one for the Intrepid that is real wood and sells for about $240.
cehasgr, awesome rims, as you probably already know i bought the same ones, but mine are 17s. I was inspired by ATF's purchase, and i think they are my favorite lookin rims for a trep. GOod luck with them
