Like some people including me pointed out, titanium screw's are a very very bad idea. They will strip very easely. Your better off with 10,9 high grade steel. Don't get the 12.9 grade, they will shear off instead of bending during a crash.

I've got the racer x and am very pleased with it. It weighs in at around 460 - 480 gram's complete if I remember correcly(arm's, bearing's and knuckle's). It is better because you don't got rear turnbuckle's(which in a crash at jumping is a real pain in the butt since they break first) and weigh's less than a ext but almost just as strong.

I'm surprised the suspension kit's don't come with the pillow ball's. But for those, ue has their own steel one's. Again, don't take the titanium version since they will snap instead of bend like steel. And to top it off, ue pb's has a extra hex in de threaded part, so if you break it, you can still be able to get it off with the supplied hex in the suspension kit.

Your drivetrain should be plenty bullet proof.
