They are a little lively.

Yeah, I've never checked a Pac spring that matched it's advertised specs. Not sure why but these are definitely 1224's and that's how they measure on my Rimac with a retainer. I checked without a retainer just to see if, for some reason they measure that way at Pac, but still not even close to "advertised".

I use those same springs (2 sets) and that's why I noticed the high rates. Never seen that but will look for it.
