The biggest difference in handling between the ES and the MP3 are the tires/wheels. If you put the 17" rims and tires from the MP3 on an ES, you'd find the ES nearly the same as an MP3.
Ummm, no. I've said before I'm pretty close with my Mazda dealership.The manager is a good friend of mine, and it's not uncommon for me to just go up for a visit. Therefore I've had the luxery of seeing just about every mazda inside out.... or more importantly on a ramp.
Anyhow, there's quite a bit of difference underneath the two cars. Tokico's, swaybars, the linkages etc etc etc. Yes the wheels play a big part, but their not the biggest part believe it or not.
I've got winters on mine now. 4 steelies. Even with the steelies on and bad winter studs, the car handles amazingly well. The winter tires I have on, and rims, are the same ones every mazda here has, and I've driven the ES with the same exact winter tires and rims, and I'm telling you....BIG difference. The suspension is a lot stiffer on the MP3, and there's just no where near as much body roll. I find the tail end on an ES just to light and eager to come around on you, and almost bounces over some bumps. Whereas the MP3 sticks much better.
Don't get me wrong. The ES is damn fine handling car. And their very sleek looking. They remind me of the old civics when Honda gave a damn about superior handling vs "practical"
But, the MP3 is in a class of it's own, and the tires aren't the ONLY reason. I remember the first time the mechanic at Mazda lifted her up just to take a look underneath.....and his jaw dropped. Next thing he's calling in every other mechanic/sales person in the store to look at it.
I've owned a couple of high end preludes over the years( 90' SR, 94SR, 97 SH), and I'm amazed at how well the MP3 handles...especially for a 4 door. You push it at it's limit, it handles far better then the ES.
As for the guy that has an ES and added the Racing Beats, and s*** to it. I'd love to see that car. I thought About doing the same thing, but then factored in the cost and just bought the mp3. By the time I bought wheels\ground effects\shocks\swaybars etc etc....getting the mp3 just made more sense.
anyhow, enough on this topic for me.
