Buy cheap buy twice springs to mind, for not much more you could get a set of Eibach pros which are tried and tested by many of the guys on here, I'm on my second Z and have used them on both, you tend to get them cheaper on German Ebay
Lowering Springs

For clarity as this point is sometimes missed.
The lowering amount quoted is for a standard car. A Sport is already at -15mm. So a -30mm only lowers it another -15mm.

Oh, so now I'm confused, I just want to lower the car 30mm it's all standard atm so is it a 30mm kit or 45mm I need?
I also have -30mm Eibach springs and can vouch for their performance, really good.
If your car is standard as mine was, it'll look far better as well once lowered.
Weather your car has sport springs at present or not, the -30mm Eibach's will be fine.

You would typically use -30mm even for a Sport. The point is whatever car it goes on they drop it to a total of -30mm.
It’s just a Sport currently has -15mm already. So putting -30mm on only drops it another 15mm to a total of -30mm.
Thats not correct mate, as Robert has pointed out, you use -30 for both, standard will then drop 30mm, sport will drop 15mm as its already lowered 15mm
IF it still has the original from factory suspension you can look on a vin decoder to see if it left the factory on Sport OR standard suspension.

And if anyone finds a genuine 15mm aftermarket spring drop then let me know. Because that would make it a straight Sport replacement and to the best of my knowledge they don’t exist.
Genuine BMW Sport springs are painful sums of money. Meaning Sport owners have little option but to drop their cars further using typically Eibach even if they don’t want to. And I don’t want to!

All of this said. Remember most of our cars are 20 years old now and springs may already have been replaced. And who knows with what.
I’ve just had to change a whole set of springs on a Sport for no reason other than it was still on factory springs on 3 corners at -15mm. But one corner had been changed, presumably because of breakage. And a standard spring had been fitted meaning the ride height was higher in that corner. No -15mm springs being available meant all 4 had to be replaced with -30mm. H&R on this occasion rather than Eibach but little difference.
The other complication having measured various sets is that standard springs of which there are many makes like KYB can vary by 10mm anyway!

If you've got a 4 cylinder Z then you're probably OK, but a 6 cylinder one may turn into a snowplough.
Sorry yes, my bad. I knew what i meant to say just worded it badly.
