    Ha its not that random, thats me and yes I have plans for a new subframe. 20 credits and Senior design aren't going to allow it until I have my degree in hand though.

          Half the stuff I'm doing or going to do, I do just because I can and its what I enjoy. In the end though I'll have a lot more freedom with the suspension design, I've already ballpark quantified the weight savings, and it should increase torsional rigidity.

            Rear subframe? I've never taken my front subframe all the way off, but I wonder how heavy that piece is. Seems that would be a pretty easy one to replace and drop weight off the front end of the car.

              I've got the front crossmember off and its not that heavy. It can easily be replaced with a new design to lower the engine but I'm hesitant on a street driven car because of the lowest point of the tranny.

                The rear subframe is a good 100lbs easily... it's a workout to carry.

                      I am pretty sure my memory is serving me right here, even if I'm off I am certain its no more than 55lb but I can weigh it again before I start reassembly over the term break.

                          Yea, I pushed my subframe up by myself with the diff and everything on there when I was installing my collars. It as heavy as crap, but not that bad. Probably 120-140 lbs with all that crap on it.

                              That is mostly going to be made to order kits for serious enthusiasts. I'd rather not talk about it until its reality.
