i've duel metal disc breaks on my x ss and for the first 2 minutes of use there great, but once they heat up there useless. I'm currently upgrading to hong nor x1crt breaks as they don't fade and have excellent stopping power.
as for the 3 speed i wouldn't bother, its just another thing to go wrong. It won't increase your top speed much, maybe 3-4mph. and it may make wheelys easier but it won't do it for aslong due to the gear being shorter. IMO you should stick to the stock 2 speed and spend the money on more usefull things like better electronics or tyres.
