Re: The do's and don'ts of Lowering
I'd probably go with either eibach springs (pro-kit) or H&R's. They may cost more, but have much better quality and are backed by a warranty.
If you have a deep pocket, you could get shocks, struts, and camber plates since your already tearing that area apart. If so, I'd go with the Bullitt handling kit, it won't lower the car as much, but it includes everything for around $500.
