| 66mm FCABS. Bought from dealer. Pic below.
Powerflexes have slightly more vibration over bumps and slightly firmer handling in general. No change in road noise. If you're looking for a best-bang-for-your-buck handling improvement, consider some sway bars, as FCABs won't help much in that department.
