So there are these pricy Fioroni pistons here:

I was wondering if anyone had tried these among the myriad of other after-market pistons? Do they perform similarly to the VRP units? Better? Or are they just the latest version of muffler bearings?

I have tried them. The do provide for very quick rebound. I ran them on a medium/high grip smooth surface and quickly took them off my car and put a set of shocks with standard style pistons on. Lap times went way down after the change. Just way to spongy for that type of track. I think they'd be good on a rough track with the right oil and spring combo though.

Thanks for the input, Apco. I found a review of the VRP pistons yesterday and those apparently do save a couple of tenths per lap, which is fantastic for a consistent driver. Would you say that you had similar results?

Not the one time I have tried them. Just wasn't the right type of surface. Best I recall there are two hole options and I ordered the bigger of the two. Just didn't have enough pack for a smooth track. On a rough loamy track I think they'd be pretty good. Just waiting to try them again.
