I was trying to get one for ages, was really hard to get one a little while back.

Ended up using the yeah racing one, which isnt bad. But from what i have seen the 3 racing one is better than the yeah one and really tough like their new knuckles and almost as good as the tamiya one.

With regards to whether the alloy steering rack is better, people kept saying it was a must, a little while back. I got rid of the plastic stuff straight away. But someone was saying the plastic one isnt too bad, but if you hit things then the plastic will warp quickly. Although the nature of the M05 is such that in my opinion even if you are a good driver you will hit things initially while you sort the car out. Generally the best thing is to run a massive amount of toe out on the front M05.
