Mad Rat is broken

[EFFX]

Hi, I bought a couple of Brushless Mad Rats the other day and took them out today for the first time, both broke but I expected that.

One popped its suspension and the others back wheel broke off losing some bearings. The cars themselves are good but I need to buy parts for them preferable upgraded ones, so could anyone help me with links to upgraded:

Rear CVD Shafts
5x10x4 Bearings
Front and Rear Suspension (Alloy)

If there are any other things that I need to upgrade please could someone post some links.

Thanks in advance,
EFFX
