That looks good too, though I don't know about the sway bars. Certainly you could go with either and it would be much better than stock. The question lies in your future plans. I would think about what you want from your car, what plans you have, etc. Do you want to eventually turn it into a handling monster or just tighten it up a little? Stangsuspension seems like a nice kit, but if you want a suspension monster, then you might end up replacing them again in the future. Sorry to ask more questions, but I feel that I could not just give advise with out asking such questions.
Personally, I would lean towards the Steeda kit over the stangsuspensions kit. I think the Steeda kit has more potential to handle future mods and HP. Hope this helps.
