Dynamite Design said:Or I could do like everyone else, and use 2 x 1/4 wall like you said, plate it all in and run fish plates, weld them on. Get less ground clearance and still weight about the same?
Your links, CL to CL, have less ground clearance at the axle end than an equal length 2"x.25" trailing arm with chro-mo plate for the shock mounts. Sometimes people do the same thing as others because it's what makes sense. Don't be different for the sake of being different, be different because it's better.
Good luck finishing the new car by your deadline.
