Reply to "Extreme Rear Suspension Compression"

Thanks again everyone for the great insight and advice. Sorry for the delayed response but we headed to the remote mountains of Wyoming for the Christmas Holiday. One of the few places left on earth without cellular service and internet. Talk about be disconnected - I had to drive halfway down the mountain to get cellular service.

The offset tool I bought to test fit the new tires is showing 13mm as optimum offset in the rear. I tried going farther inboard to 18mm but the driver's side tire rubs very hard on the upper inner frame rail with the suspension compressed approximately 1 inch from ride height when set at this offset. Likewise, at 13mm offset I will also still need to roll the rear fenders due to rubbing issues.

This is not quite as far inward as I would like (love the tucked in look of the rear tires at 18mm) but 13mm appears to be the best offset on rear wheels of my car. Also at 18mm the passenger rear tire rubs on some the exhaust, however, this would be fixable as George had mentioned.

The front suspension with the 245/35/ZR18 seems to be best at an offset of 19mm. However, the passenger side has issues with rubbing the window wiper motor cover at full lock with this offset. With a little fabrication of a different cover it should be no issue. I tried 18mm as recommended by others but I had issues with the front tire rubbing on the front portion of the fender when compressed.

All I have so far. Any other thoughts or recommendations out there? Hope everyone has a safe and Happy New Year's Eve tonight.
