what car is it?

I had whiteline flatouts (springs) in my 02 STI. Were quite low, and was a pretty stiff ride. However, I think I wish I had at least gone some HSD Coilovers (see BALISTC) At least you get the choice of adjusting ride height as well as camber and other bits and pieces.

Those coilies will set you back about $1299 to buy, plus probably a couple of hundred to get fitted.

Springs (whitelines) will cost you around $600-750 fitted.
