    We're a first year team with a $20,000 budget. I'm not even looking at those brands.

    Basically, any piece of crap that will turn my wheels for a reasonable price is up for discussion.

    Longitudinally welded tubing for suspension?

    How bad of an idea is using ERW tube for pushrods and a-arms? The seam adds another path for failure, but assuming good quality tubes, are the stresses enough that we need to worry about failure in...

    I'm very interested in this set. However, I've never attempted to revalve dampers and am worried about whether I'll have the time to learn. Can you speak to how difficult the revalving process is?...

    Just a heads up, the first link in the original post is active (the one crossed-out). It doesn't have everything the newer link has, but anything helps.
