Can anybody guess what coilovers these are please?
The struts look to have been painted in past.
You can see S.W..... The rest I can make out written on springs








You can see letters sw here, rest I can't make out

 

Well I've got to bottom of springs that are fitted.
Which are a 'upgraded' swift Spring which is a aftermarket part or upgrading to a firmer spring for race/track.

Copied from swift: SWIFT Bronze Metric Coilover Springs are highly linear, fewer winding springs that reduce unsprung weight and increase performance. From Formula Nippon to Le Mans, these innovative springs continue to make them a staple in the racing industry. An absolute perfect upgrade for those looking to hit the track. Why? The engineers at Swift researched extensively and formulated a unique blend of metals they call H5S.TW, a unique alloy that carries a wide variety of benefits and virtually zero drawbacks.
