Chances are that the lower the car the more bounce you're going to get because they need to be stiff. Tein are the best for suspension but $$$$. Instead buy some nice gas shocks such as Tokico or KYB with Tein springs(Luxury Master Springs)Optimize performance and quality without sacrifycing comfort. The problem is that they only drop the car about 1.2" to 1.5". That's the cheapest setup, if not then go for Tein coilovers which are the best but cost $$$$ maybe $750 for the Tein Basic Damper
