Well, this wheel search is more involved than I thought. Has anyone fitted MRR wheels to their Challenger, especially either the Ground Force series (GF9) or the FS1/FS2 types? My Challenger is 20x8, 5x115, OE 24, and BS 5.44. Even if you don't have the MRRs, perhaps you might know if such things would fit properly. The MRR wheels are 20x8.5, with offsets in the 20-25 range.
