If you're looking to go that low, my recommendation are the Eibach Sportlines. Though, I do not recommend slamming your car that low. The adverse effects of lowering the ride height will cause additional stresses in areas of the chassis/suspension that will in the long run make those components less durable. However, the choice is yours.

You can try the K-Sports out and let us know how they work if you're willing to give them a go. We always appreciate guys trying out new products and giving the community their evaluation.
