Hi, i am running all stock on my RB6, last weekend i was racing in a national cup here in Norway on a very though track with clay compund, but i would rather say it was like concrete. Not a single part cracked even if i had some hard hits. At my local track we have astro turf. My buggy handles really good, i wouldnt change a thing. The only weak point i have ond is the rear hubs. This is my history of destroyed parts on my RB6. 2 rear hubs, 1 rear suspension arm. And i have driven about 70-80 batteries with it, so i am very satisfied with the buggy
