I got steel spurs on my SCT410 and EB48, and my daughter has stock on her SCT410, having run 1/8 e buggy from the early days when we ran the Neu motors and 25C was "high", I had a total of 1 nylon spur pop on me other than the two toasted on my teknos. And they went because I didn't know you needed the steel with a long shank so had two puffs of snow.
