Wire Diameter of 2.25” Linear Spring

[Nardo S54]

Not E46 specific but figure enough track folks here who might be able to answer. For those running 2.25” linear springs, can you verify the wire diameter of that main spring (i.e. not referring to tender or helper springs). Assuming the variance among manufacturers is limited so I’ll take any “confirmed” number as a proxy. TIA.

Wire diameter is going to fluctuate based on rate, length, travel, coiling procedures, etc.

Manufacturer hit me back. For my 6” linear spring, the diameter is approximately 10mm.
