You need to talk to a machinist/engineer who knows exactly what components and what loads are going to be put on these parts.Why are you doing this ?? Anytime you try to "re-engineer" something you will most likely find it wasn't as good an idea as it seemed. There are so many high quality, tested components out there that those kinds of things are usually for week-end toys. Not for street consumption. And race tracks have tech inspections, and require certification on certain mods. JMO
