Somebody brought one to my last autocross on Michelin Sport Cup 2's. It was extremely fast in between the corners, but too large and heavy for our tight course. The body roll was hilarious. Too much tire, not enough suspension. I beat it by 1.2 seconds on a ~ 37 second course in the CTR. On a course with longer straights it would have been difficult to beat.Track Mode is only for Performance. I do not believe you can enable it via download on the LR AWD, but you can get the Accel Boost.
For street driving, Track Mode is superfluous, but for track driving, the Performance brakes and suspension aren’t up to par.
It’s a strange position to be in. But honestly the best move if you actually anticipate track driving is probably to buy a Performance model, sell the wheels/brakes/suspension to an LR owner, and replace with higher capacity/better performing equipment. If you’ll never take it to the track, just get the LR with the 19s, put on some PS4S, and download Accel Boost.
