My thought is that if you feel that you need the bigger brakes to stop safely, then the question is answered. Personally, I feel that stock sized disc brakes in good working order with high quality pads are just right for trucks. If you were going to take it on the track, or have big five spoke wheels so you could peekaboo with your brakes, maybe that's a different story for performance or visual. Also if you were going to a wheel and tire combination that was considerably taller than stock, bigger brakes help overcome the added leverage of the increased radius. A further consideration is weight. Larger diameter wheels with low profile tires can weigh significantly more which can translate into sluggish acceleration - caveat: probably not a problem with 489 fricking cubic inches pushing your truck :) If you want that distilled into an opinion, I'd be a bigger fan of smaller rallys and putting your Baer brake kit up for sale.
