I agree, it's a very solid and easy to setup car! I haven,t had any problems with the shock towers ... Yet...
And haven't read about many either...
But the carbon towers mentioned above do look great and seem strong. Certainly not a bad investment if you have a few $ hanging around...
With the stock setup I was pretty much just as fast as I was with my B44 last year. I've started slowly making a few tweaks here and there, but nothing major except adding weight under the Lipo packs to get it to 1800g. That's all!
If you can't get the parts in the UK, there are several online shops in Japan that have or can get parts and ship them fast (

It's a great kit (beautifull quality). You'll love it...
