For a set of 928's to be 180@1.92, they would be a bit of an anomaly.

I've used dozens of sets of those through the years........and I don't recall seeing any that were 180@1.92.
The spec is 160@1.880/383@1.250..... and they are usually close to that.

It's a suitable spring for the type of cam I'd use for the low maintenance bracket type build, but is probably going to be a little light over the nose for that UD cam......especially if they are installed at 1.920.
