I've broken three in the past three weeks. Those were broken tapping the wall, not major crashes at all. Luckily, two were during practice and only one was during a qualifier. That said, I've been using IRS ride height adjusters for two years and up until now have never broken one. The plastic does seem to be more brittle and for the whole number adjusters (0, 1, 2), I'm switching to CRC. For the half numbers (.5, 1.5), I'm still using the IRS until I find something else.
