The result is inconsistent performance over time, faster internal wear and diminished grip. Cavitation prematurely ages all internal components and must be avoided in any quality shock.
However, the lack of even a minimal gas charge and the inherent twin-tube design causes cavitation (foaming) of the shock oil with even moderate usage. It does have independent double-adjustment of low speed rebound and bump which can be a nice tuning aid for the serious enthusiast. # Background: Surprisingly, FM chose a degassed twin-tube for their high-end suspension. # Flyin' Miata AFCO - aftermarket, American(?)-made twin-tube, digressive character Surely they can't be as bad as that? Is this just a rival vendor throwing opinions around as fact or is there some truth there?
Reading the review of the AFCO on the Fat Cat Motorsports site ( ) I'd be crazy to buy them (I've copied and pasted it below). Hi, I'm looking at suspension options for my 94 R-ltd and looks like it's going to be the FCM set up or the FM AFCO.
