so it stands to reason that the ghea pistons fit the shock body more precisely/ tightly and still have the same hole diameter.
using 30 weight in B4.X and B44.X there was way too much pack. then dropped to 25 weight oil simply too much pack as there was no "blow by"
I think someone called the oil that would pass by the side of the moulded associated piston, "blow by".
so without the blow by and using these pistons i'd have to drop to 22.5 or 20 weight oil.
bummer- got plenty of 25 and 30 weight. not keen to buy more oils at the moment.
fact it that I still saw guys with 'out of the kit' B4.X and B44.X going faster. this upgrade might have to go into the 'waste of r/c dollars??' thread
any ideas ghea piston people???? thanks in advance.
