Nice writeup on the ride-height lowering - using the lowering springs. However, didn't I recently read somewhere that if you use the stock shock/strut tubes for lowering the car --that they don't last very long at all?
I see. So anyway, what size tires/wheels are those VX's? According to this website: http://www.miata.net/garage/tirecalc.html if I change my current setup of 175/70/13's to 185/75/14's, my speedo will be underexagerrated by 6MPH, therefore increasing (to my knowledge) my effective MPG. Of course I'll have a slightly larger contact patch with the 185's. But probably not enough to make a difference. As long as I can find a lightweight setup I'll go for it. As it stands right now I only run with +2 PSI above MFG recommendations. Let me know how your car rides with stiffer suspension COMBINED WITH high-inflated tires. Thx.
sorry, I meant to express my definite WANT for the underexagerration. As long as I can run a larger diameter setup I'll be running a higher MPH at a lower RPM (even though my speedo won't show it). I DO want this. Call it a cheap way to change my effective gearing since I've got the larger circumferance, taking longer to complete a single revolution in a given gear. I want this. I'm sure I'm not the only one who does.
