Nice thread necro. But no, I tend to be honest with any and all upgrades. I feel that pooty's flatface handled paint slightly better in my GTi (sans spring), and would be interesting to experiment with the spring w/ viton valve o-rings to see if the wear problem could be overcome.
Although it cracking a bolt seems a bit excessive. Maybe one of those things you buy if your in the deep of winter and want an option to help overcome FSDO if it rears its head.
