how much yen was it? im sure in japan you can get coilovers for less than you can here, and its about 2grand for a nice set here. For typical point of reference, 100 yen is about 1 usd.
and who determines what fast is? fast acceleration? 1/4 mile? theres too many options nowadays to say what "fast" is.
for me, fast is when you hit boost and you're thrown back into your seat
