Been away for a while. No car for 6 years, miss my FX. I'm looking at 2014-2015 QX70s. This might seem trivial, but I really like the 20" wheels. My FX had them (sport package). If I recall correctly the sport package had a stiffer suspension than the base model FX. Now the QX has no sport package and I've only seen 20s with the touring package. Does the touring package or the premium package have a different suspension than the base, or is it just the wheel size? I test drove one 2014 with 20's and it was quite similar to my FX, maybe a bit softer ride, but it's been a while. Any info about the 14 and 15 QX70s will be appreciated.
