Lazer ZX-5 upgrade help

[littlened]

ok, I've decided to stick with what I have and upgrade it bit by bit to make it a better car.

I've ordered the parts needed to replace the plastic diff shafts with metal ones. That should help the car cope with the non-stock motor it's got in it.

From what I've read the plastic the car is made from on the RTR isn't as good as the SP, I don't know how true that is, but whatever I break will get replaced and I doubt the quality of the plastic is going to make much different to my driving (which isn't good by the way).
