I would suggest upgrading your chassis to include the
competition chassis. The plastic pieces in this kit are a little more durable and will probably last longer than the stock plastic your currently have on there. I cracked a stock front upper cover and quickly replaced it with one from that kit; much more durable feel and seems a little more precise, too. You could always just dump money into alloy, too.
Glad to see you've caught one of the greatest diseases known to man. Put your wallet in a safe place.
