Which version of the car are you running?
In 2008 (car built Oct 07 and raced out doors most of the winter too) with the SP I broke 2 front towers, one front arm and stripped the threads in one rear hub (car never had a transmission component replaced in it's life till it was sold!) .... considering the abuse I throw at it that is a damn reliable car!!!!
The FS has been a little bit more fragile in terms of front shock towers but I have not broken anything else AT ALL this year!!!! I have now concluded that as I was pushing the FS MUCH harder than the SP during the initial set-up phase and also doing it in race conditions (in the freezing winter) rather than on an empty track as I did with the SP it was me rather than the quality of the Kyosho parts which caused those failures.
That said I now run a front shock tower brace for piece of mind but really doubt it's actually needed!
One of the reasons I'm so much a fan of the RB5/ZX5-FS is the quality of materials and overall robustness of the designs.
