FYI: Not knowing what tires you are using The following may apply:

275/60/15 (rears) and 255/60/15 (fronts) tires on a superformance should be adjusted to 27" from the ground through the center of the wheel and to the middle of the body wheel opening. Like Bill Wells said (hello Bill).

17 inch wheels should not be adjused any lower than 26" with a caveat - if your using 335/30/17 tires on the rear they may rub on the inner body wheel well if you get it close to 26". 26.5" may be more appropriate.

Been there done that.
