If I wanted to add the K&N filter and also do Eibach springs would it in any way void any of the warranty on the car (I'm leasing mine)?...What is a good price for Eibachs and how much for installation? Can a Infiniti dealer do them? What kind of drop would I get w/ the Pro-Kit(1", 1.5", etc.)?
Any feedback would be appreciated. Right now I have the stock sport suspension on my car and want to keep the stock tires as well.

 

I would think the K&N would not but the springs may affect the warranty.

 

If you have a suspension related issue, that would cause the warranty to void, but it's not likely. Nor is the K&N for that matter.

I have them both done.

Just retain your stock spring so you can swap them back when you return the car.....

Do you have any pics of your ride?...What's the drop on your car?...I wanna keep the 17in wheels and put on the pro-kit...Will I get a 1-1.5in drop??..How much did you get your Eibach's for?? What is the ride like? Any major difference noticeable besides the better cornering, etc...??Right now I have the sport-tuned suspension and ride is great......
