A good choice.

I have just fitted one of Bonnie and Clyde's kits as sold by Westy on here to revive an old .177 HW80.

You get a variety of brass washers/spacers for the piston and a couple of power bands to use on the spring guide.

In my case, no power bands and the thickest brass washer plus the thin delrin washer/top hat bearing in the piston provided the desired result.

Gun is now a joy to shoot @ 765 -770fps (where I like the power of my springers to be) with JSB Exacts which equates to around 11 ftlbs.

You won't be disappointed if you buy the kit and use the various lubes supplied correctly - Westy can advise you on what to use where.
