I found a set of Eibach lowering springs part number 5545-140, has anyone installed these on there Mazda3 yet? If so how is the ride?I still have some research to do before I consider buying them since I changed the wheels on my Mazda3 from stock to 18 inch and don't want issues with rubbing.

I ran the Pro-kits and loved them (very mild 1" drop) Ride quality was near stock. Not sure what the part # was.

Measure straight up from the top edge of the tire and see if you have 1.4 inches above the front and 1.2 inchesin the rear plus room for suspension movement
