I have not used the extended chassis yet but between the Avid aluminum and carbon they both have their purpose. The aluminum extra weight on higher bite clay tracks noticeably settled the chassis more and made the car more stable to drive hard. Carbon fiber outdoor loose dirt dominated with alowing the car to be driven harder and find better traction around the track. More forgiveness jumping and powering through low bite corners. Low bite I dont feel the longer chassis would help much but high bite yes.
