The one thing I have'nt been impressed with my X since day 1 was it's highway manners. In fact it was plain hard to keep in a lane over 60 mph when I first bought it. Now after 2 alignments, 3 wheel balances, and a set of used OEM 5100's I have to say the X feels damn nice over 55 mph's. On a very straight (and safe, no cars ) stretch of interstate last night got it up to 85ish following a G35 coupe, felt like a champion. Just another reason to love my gas guzzlin' beast!

Weird, I've got no complaints at all, cruise in the 70s, have had it in the low 80s.
