Great to know it comes in fiberglass...I can repair that easier than carbon fiber (just in case!). RK is short for Rock Krawler correct? I can easily search online. Oh, and whenever you decide to change the RIPP SC out for anything else, let me know...this 3.8L is killing me! I have to re-gear with 37s for my on-highway sanity/patience! With the auto tranny when I'm home in Texas the speed limit most roads is 70-75 and no one drives 75 (standard rule is add 8mph). Please advise as I trust you guys on advice: 3.8L/auto equals 5.38s to put the engine back close to the power band? Thanks-LongbowDriver
