The slant 6 bars will work. It will just sit a bit lower in the front. Using fiberglass and aluminum will definitely help :-). A customer had a cloned A990 car in the shop about a year ago and the builder had used all aluminum bolts which were drilled, fiberglass bumpers and the whole nine. The guy had somewhere around three to four grand in custom fasteners alone to shed weight. Wild stuff! It certainly helped shed the pounds. Oh, it was a non competitive street driven car as well......?
