Sport suspension uses different springs, shorter and with a higher spring rate I believe.
I've also read that the ECP parts are rarely correct, so perhaps get a part number from Sachs for the M Sport replacement and confirm before purchasing. Aside front that, https://m.ebay.co.uk/itm/Suplex-Coil-Spring-Rear-Axle-OE-Quality-06231-/292040912476 these are the replacement springs most use for the Sport suspension.
Rear drop links are these https://m.ebay.co.uk/itm/Lemforder-Rear-Anti-Roll-Bar-Stabiliser-Drop-Link-Fits-BMW-Z4-ARB-/351102756300?fits=Model:Z4&hash=item51bf5ae5cc:g:l0EAAOSw2xRYePnt&_trkparms=pageci%3A18a3e8d7-9a22-11e7-adeb-74dbd18021e0%7Cparentrq%3A85f090f215e0a86bc46b9cb3ffe25e21%7Ciid%3A18
