What is the general opinion on using the aluminum castor blocks and steering arms? I was looking at the diggity and integy parts but am a little reluctant to order. On the integy rear hubs, does anyone know if these are 1 or 0 degree? Are they heavier? I looked on the websites and couldn't really determine. My concern with aluminum parts has always been transferring the force of a hard hit to something I really don't want bent or broken. I would rather loose a suspension arm than a bulkhead or chassis plate. If they are not too heavy I was thinking of the blocks & steering arms, but not the susp. arms.
thanks in advance.
