As far as mild lowering, you want to stick with name brand is the biggest part. Your whole car and the safety of others rides on them. Id stick with Eibach, Tein, Megan, etc. for lowering springs. Of course pair then with new shocks (Tokico HP are a good budget for mild lowering). And dont forget the camber issue.
If you go the home page (2gnt.com) and click on Cars, then maintenance and modifications you can drill down through there and find what you need, as well as learn a ton.
