I have snapped the front off my X6 Squared chassis, and also done a nose cone on my four gear.
The squared went when I was going full tilt down the straight and hit an RB5 which had rolled onto the straight, snapped the top brace to. The nose cone on the older chassis was done indoors when i got punted off at the end of the straight by someone I was lapping and hit a wall. Both snaps were pretty understandable with the force of the impacts though. I have been racing it x6's over a year and I still have two packs of original rear wishbones that i brought when i got the conversion kit never opened, Done two toe in blocks but haven't done one since the new design came out and thats it.
Has to be said my spares box very rarely gets opened these days.
The squared version I have is brilliant though, when building it up it was so much easier than the old one and the quality of the parts is soo much better, and now I have sorted out the balance on my car it feels so much tighter than the old one. Keep up the good work chazz and crew.
