He doesn’t like them because he says since it’s a 2 piece damper that isn’t...I can’t think of the word he used but it’s how the OE dampers are made with the hub and the ring actually fused together. Any way, he says you can see with test equipment the outer shell getting off center to the hub because they are not fused together. I have never seen it myself, but the guy says he’s seen it. That’s why he says to run a damper that is put together like an OE damper. And I disagree with that. There is too much data out there that an OE style damper has way too narrow a tuning range and any change made to any part of the crank, rods, pistons, pins, rings...any thing that is related to the crank changes what frequency needs to be controlled. No rubber damper can do that. I know they are everywhere at the track, but any track is a monkey see, monkey do situation.
