I have given people duff info. about harness specs for this year for speed events (as advised to me by a senior Scottich scrutineer!!!) the expensive FIA spec harnesses are only a recommendation for this year in speed events........my cheapo 25mm harness will still work this year!!! Hurrah!
The big belts were due to be brought in but at the annual speed meeting it was decided to opt out. I suspect they are coming at some point anyway as pretty much every other branch of motorsport brought them in this year.
