I'm going to be replacing the front suspension in my '79 LeMans. Are there significant advantages to going with tubular control arms? I figure I need to remove them anyways to replace the bushings at least, and I've seen tubular kits that come with the bushings and ball joints already on them. Obviously it would be cheaper to just have new bushings pressed in and replacing the ball joints myself but if there are big improvements from a tubular swap then why not.
