^^ that's not good at all. What cams? I've had my GSC springs for about 4 years now and 40kish miles with a bunch of track time with no issues yet. Sure hope they continue to hold up.
I would not recommend using GSC springs so go with Kiggley's. Many folks had springs break, taking out the motor. GSC would blame the customer stating it was installed incorrectly, which I suspect is complete garbage. I had one snap after a few thousand miles of driving. Called GSC and they were only willing to send me 1 new spring. Long story short, purchased a set of Kiggley's.
GSC had some issues back in the day. Failures are not common place now. I know plenty of people running around on GSC springs, including myself for several thousand miles without issue. And as with any racing part, I'm not surprised they didn't exactly "warranty" anything.
