After shortening them over a 1" , I shaved off some 2 LBS off them . I also punched holes with dimple dies in areas of the car to save more,trying to concentrate more on the top half of the car to keep the center of balance low..I was thinking of making the upper door hinges out of aluminum plus some other parts. I have some scrap titanium around the shop I thought of using in some areas too. I am always open to Ideas from everyone here to shave more pounds off without effecting strength.
