I'v seen that alot of people on the forum who have already added these products. I just wanted some reactions to how they have liked these products and if they are worth getting.

Some other questions:
For the Eibach kit, does anyone have a website that they have ordered from and gotten a good price.
----Also how much have you guys payed for installation? (any shops in NJ who will do it helpful)----I know that the kit increases handling and feel, but does it also lower the coupe at all? if so, how much?

For the CAI, i have seen many people with the Injen and some with Stillen. Now that some of you have had these in your cars for a while, which do you prefer?
----If there are any NJ owners here, please let me know if you know any places to get these installed and how much i should expect to pay.
