I emailed DP Accessories to confirm the installation of my 2008 Charger R/T with Performance Pack and they were very helpful and friendly. These fit and look great. I was concerned that the design would be a little different than the original, but now that they are on my machine I feel that they look a lot better than the OEM cleats and work a lot better. It's too early to tell how well they'll hold up, but the triple-coated chrome looks like it's going to last. Attached are photos of these and factory tunnels. Edit: After a little more than 3 months, the tabs rust. Added follow up photo. look elsewhere
