I guess that depends on your driving skills, but for the most part I guess I'll give you the typical answer. Bearing carriers, caster blocks, all A-arms, shock towers, and a front bulk head. That's what I'd go with. Any thing after that, you just need to slow down. If your still a rookie I would try to start out in the stock class, because the slower you go the less you break. Not only that, but you can really get a good idea for how the car feels, instead of just powering through it.
But like I said I don't know your skill level.
