Megans are JUNK.

A simple shock dyno test proves it.

Bilsteins, on the other hand, are GREAT shocks, and are easliy converted to take-aparts for revalving.

I would avoid used shocks of any brand, unless they come with a recent dyno plot.

Bilstein, Koni, Penske, Ohlins, Dynamic Suspension, Sachs. Avoid all else like the plague.
