My ERA sits as follows:
Rear and Front
Gnd to top or wheelwell flare
25-7/8 inch and 26-7/8 inch
Frame to Gnd
5 inch and 5 inch
Tires
255/60-15 and 215/70-15
This is not a real precise way to set things up as different bodies may have had their wheel well worked slightly differently.
Edit - Forgot I lowered the rear suspension for a frame clearance to 5 inches - corrected above.
