OK...another question for you guys. Which air dam is the best? More specifically, urethane or fiberglass. I like the ones that MSA offers (minus that new one) but dont know for sure which type to get. I know noone personally who even has a z car let alone an air dam. Thanks for any advice.

Hi

The polyurethane airdam would be more resilient and less prone to cracking if you were to bump something. important if your car is low in the front.

from what I know the middle of the urethane dams droop so you would have to fabricate a support to hold it up.

It would be awsome if someone made the BRE type "spook" in urethane, as well as the ZG flares, instead of fiberglass.

i highly recommend the urethane , replaced several before I learned , between speed bumps and curbs when parking its just not worth it , the right painter can add chemical to amek ti more elastic to it less likely to crack as it flexes
