I don't think 19 inch wheels will fit without some really low pro tires and some modifications. You need to decide whether you want big ass rims or speed because the two don't go together really well. Ground Control coilovers are a great coilover at a pretty good price. You should also consider camber kits when going that low too. What do you plan on doing HP-wise? I buy most of my stuff off ebay from reputable dealers, so that would be a good place to start looking for what you need and how much it is going to cost you.
