The proper nomenclature for the tie strap I believe should be front hinge pin brace. Ill check the manual. I think if Kyosho does not offer the parts in question in aluminum, then I will end up buying some from the BJ4 and making it work.
Its interesting to note that the parts I did mention come out of aluminum on the BJ4 (or at least on the new kit being released). Jconcepts also gives you the option of heavy duty front suspension arms. I suspect these guys have done their homework.
Hopefully Kyosho will follow suite and make their buggy on the same level.
