I've been thinking about doing the Bilstein suspension mod to my 997tt. But since we have so bumpy and harsh roads (even on highways) in Istanbul, I've got some doubts about doing it.

Would you suggest me to go for it even with those disadvantages? I'm not going to drop it even if I do the mod. Is there anyone with the same situation and did the bilstein? I'd appreciate some feedbacks..

thanks in advance
