I have only had my 08 LX570 for about a year now, it's seen a lot of wheeling but this past weekend in Telluride was the first time I have really given in a proper flogging. Running 34" x 11" R 20 Falken AT3W at 18PSI, we had side by sides and dirt bikes pulling over to let us pass. Really hitting the same pace I'd run in my old FJ with King's all around. Surprisingly it took it all and didn't bottom out once despite getting airborn several times and hitting some water bars and whoops at a speed I initially expected to produce some rather violent results. Other than tires my LX is stock though so if the AHC would hold up as you start piling on weight I can't say.
