Let's kick this one up a little.
What has everyone been doing to their cars lately?
I bougt some 3racing ZX-5 shocks, with some genuine kyosho pistons and springs. I haven't tried them yet because I broke my arm while racing mototcross

.
I also bought some Fastrax Turfripper tyres, which are very good for the price I think. I tried them just before I got hurt and I was impressed, especially for the price.
