I have a 2001 I30 and I currently have 20's on it, I want to lower it as well. What spring set up should I do ? I had Eibach Pro Kit in mind and also H&R's what do you think Would look and work best?

 

Tein Super Sport Coilovers

 

I have the H&R springs only adn if you look at my sig this is how low my car is. Stock struts for now. I thik they are pretty good but I have nothing really to compare with other than stock.

 

If you can afford coilovers get the JIC's.

I have the Eibach kit with Tokico Illuminas and love it. It isnt an extreme drop but it is probably the best for handeling. It gave the car a more aggressive stance and really tightened things up. It is a ton of fun in the twisties. Some dont think the drop is enough, but it is perfect for me. I dont scrub on any driveways or anything and the drop is nice and even.

You can get them from SWA and they will give a 5% discount to org members. That is the cheapest I have seen on the eibachs and illuminas.
