Even if the carbon front shock mount looks nice I'd rather have the standard front shock mount snap in a crash than snapping the front of the chassis off which will happen if you stiffen the shock tower too much...
The brass bulkheads are nice though to get a little more weight over the front axle. Any other shiny bits are a waste of money and usually do more harm than good. Aluminium wishbones are a big no-no.
