Thanks for all the replys. I was just very surprised in how it handles. The AWD system is working, cause it helped me out getting up a hill thats ive got stuck on before. Just was very surprised in this cars reaction off the line turning. It has a set of bridgestones on it, not sure which ones. would have to look. It acted very much like a RWD car w/o stablilty. Ive driving in the snow one of my friends 7 series, and when stability is off. I could spin the car on command, but with the system on, theres no way to spin it, it reacts instantly to keep you moving where you want to. The VSC on my RX didnt react till I was almost sideways, I didnt have a problem countersteering to correct for the spin, and I was able to control it every time it did, just scared the living crap out of me, was not expecting this type of driving trait with a AWD car. The car really felt like it unloaded the front, and sent everything to the rear, cause it was a delay from when I started the turn, to when the rear came out.
Im not that impressed with the tires the lexus dealer put on it, they replaced the fronts when I bought the car, they matched the tired, so they are all the same tire, The tread doesnt look very aggressive @ all, more like a summer tire vs. SUV tire.
