I can vouch not only for the CAT but most 1/10th buggies feeling fragile over the winter months especially with the cold weather. I race at Oswestry Indoors each week which is a fairly tight and quick track but as we race on a showground there is no heating and the temperature outside is the temperaturn inside!! We ran last week while the temperature was -7!
I have managed to run through a number of wishbones, front shock mounts and a couple of shock shafts in recent times. However it's not the parts it's the driver shaking in the freezing conditions
