Plus, I didn't just put tein coilovers on - i put cusco front and rear sway bars, tein tension rods, tein tie rod ends, toe control, upgraded upper and lower control arms....
when you just upgrade the springs.....or even the springs and shocks....you are only changing one part of the suspension...the rest of the suspension is designed to work with the original spring rate, height etc of the stock engineered suspension.
Not to mention, that the cars ability to hold itself together, was designed based on the bumpiness of the stock suspension setup - over time, you will begin to hear rattles.
the mazda 3 has the latest technology as far as suspension goes....until other suspension parts become available - in my opinion, you are doing yourself a disservice by lowering it.

The 240sx has been around for a while. They have been on the track both in Japan and the US for years. The availability of aftermarket suspension components is huge in comparison to the 2004+ Mazda 3. We work with what we have.
Most spring manufactures have an R & D department and don't just pull springs out their collective a$$es. I'm sure it's not as intensive as say a race development group, but I'm sure it will be fine for the 3 years I will own this car.
