Jason, your explanation, no doubt, helped explain it in laymen's terms

Good writeup, seriously.

Thanks for all the replies and advice guys! Much appreciated. I guess I really need to look into upgrading the car's handling as recently I took a turn out of an highway exit at only 90km/h (est. 60mph), the car's pretty unstable...

Just installed the FD springs, and can I just say the car now feels fantastic. It feels as if its a much smaller car now, almost NO body roll, you can even tighten your steering on a fully loaded corner aggressively and feel very secure about it. I dropped the car about 1.5 to 1.75 inches and i feel that this is perfect for me, although may be much too stiff and low for most peoples daily needs.

With my set up it feels as if the car is more composed and comfortable in a weird way, almost as if these springs are the right ones and the stock springs are too soft and tall for the suspension geometry. I track lots of different cars including the QP, and with this suspension set up, i feel as if it can definitely hold its own agains many more purpose built cars. I used to think the panamera was more planted and agile than the QP, but with these springs, I can now confidently say that the QP is still the ultimate four door supercar in every way.

Thanks again Jeff for the fantastic service, your tech really took the time to make sure everything was set up properly, he works methodically and precisely.

FD springs highly recommended.

I have not upgraded my car, yet. However, I think I can speak from experience on Singaporean roads and advise Maxspeed185 that, given the healthy nature of Singapore's asphalt and general lack of concrete roadwork and speed bumps, he would be well off with a set of sport springs and a 1" drop. There's no real need to worry about damping in a country with roads smoother than Pocono Raceway.

Noted and thanks for the advice Briik. Cheers!
