You will really need to be at the 2.1" ride height setting to completely clear a 295/70R18 on the stock 18x8.5" wheels. If you add BORA wheel spacers, you'll likely get some valance rub, due to pushing the apex of the tire out to where the wheel well curves back in. The rub could likely be solved with pretty minor trimming. Ride quality complaints are partially due to tire choice, though the Bilsteins do use spring preload on the stock spring for their ride height gains, which causes some amount of stiffness. My personal opinion is most of the stiffness complaints stem from running E-rated tires at too high of an air pressure. An E-rated A/T at 45psi or so still stays pretty smooth, despite the extra plys, though a P-rated tire will have an even softer on-road ride.
