This is a response to the brake dust issue. I had a 2004 Neon srt4 and it produced a lot of brake dust as well. When the srt engineers were available on srtforums we all asked about this problem. They said they were working on it and had a few possible solutions in the works. I heard that the problem got better on the 300, Charger, and Grand Cherokee SRT8's. I will have to wait until I get my car to see if the Challenger is better. This is a known issue with srt vehicles and it looks like we will have to live with it. My srt4 wheels looked like I had driven through mud when I returned from a "spirited" drive. The braking was so good that I just grinned and bought a vat of Mothers.
