Are the springs different between S and non S models?

[RobbyNZ]

Hi all,

Recently purchased a used 2000 boxster S. Its almost 100% stock apart from being on H&R lowering springs (photos).

The height is a bit annoying seeing as my driveway is akin to Mt Everest and as a result of the lower height the camber on the back is slightly out (and camber wear on tires).

Are the non S model springs the same? or close enough? Im sure they're not, but someone is selling a complete 1998 set on the New Zealand version of eBay (trademe) for the equivalent of about $70 so its hard to pass up.

Any info would be great.

Cheers!
