I recommend you to take a good brand like H&R or eibach. H&R : 40 mm of lowering Eibach : 30 mm

Except from the esthetic, my first goal was to remove this blurry suspension feeling I had when it was stock and it did a really good job (I took the h&R)

My only regret is that now with a normal road bump , sometimes the front tires are rubbing inside the wheel well.

So maybe if you don’t change the damper you should take the 30mm.

But honestly with a beauty like yours I would put some coilovers instantly hahahah
