Those springs are actually very highly regarded. Especially amongst the AWD guys. They are the only spring specifically designed for the AWD model. I’ve heard great things about their ride comfort, etc. Not the lowest drop possible (guy on page 2 is probably 1.6").
Stretching tires? Meaning as much as I can fit on the rim? No. 245/40/21. Now you guys are making me second guess my decision. :banghead
