That's actually not a bad weight for a chassis (in my opinion, of course). What I like about heavy chassis' is how your center of gravity turns out when you're all finished.

With a chassis that is less than 60 pounds, a majority of the weight is going above the chassis, raising the center of gravity to a less desirable place. Our center of gravity in 2007 was seriously at the bottom of our chassis. Teams would really have to try to get us to tip over. That chassis was probably close to 80 pounds.

This conversation about weight is interesting. My team's did a swereve steer this year, it weighed a little over 90 pounds. Once we added the electronics and compresor it weighed 100 pounds. Then with the battery it was closer to 110 pounds. All of this was about a half inch from the ground(maybe an inch).
