Blake, I haven't had a chance to take a measurement, but what Tyler said is the case. I didn't adjust the coilovers at all when I installed my 18" wheels. The suspension drop is still 1/2" F and 1" R. Then the smaller track tires drop the car another 1.2", so total drop is about 1.7" F and 2.2" R. Hope that helps. I can still take the measurement if you like.

What axle problems are you having? I have an issue too, but it was there before I dropped the car. At 90+ MPH, there's a pretty good vibration coming from somewhere, it sounds like drivetrain in the rear. Not sure what it is. It's as if something is out of balance in the differential or the half shaft assemblies. It has me concerned. So far no problems other than the noise. If anyone has any thoughts, please let me know.

Yep, that's pretty much the same as 1/2" F and 1" R. For optimum handling, that's the drop.
