Hello everyone. I am new to this forum and this is my first post. I hope to get a charger real soon. My question is about the road and track package. From what I understand you get 10 more horsepower when you select this package, along with better susp., seats, etc. What in the package gets you the 10 extra horses? And can you really notice a difference between the reg. rt and a rt with the rt package? Thanks in advance guys.
