SWEET first bot. there is another member on here called virus bomb that started his showcase with a 36-HS and hes regarded as one of the top stock builders around here, maybe you looked at his showcase while lurking?
only advice i can really give is that this upside-down U shape your using isnt really the most weight efficient, chassis weight is calculated off of surface area and not volume. apart from that this is probably the best its going to get.
welcome to the forums and hope you enjoy your time here :)
