WHAT DOES E46 COILOVERS MEAN?

The pistons inside these shocks are 57mm (I think). These coils are clean up. The green anodized end to the bodies is good, plus the Swift springs truly glimpse good. They're corrosion-resistant, but I however wouldn't push on them when there is snow or salt on the bottom. Hold the slammed vehicles inside the garage for the Wintertime, gents.Ohlins
