When placed in park and the brake is depressed is the car supposed move a bit?? Everytime i do so and its on an incline it does this. Even if its no on an incline it does it. Maybe 2 inches or so. Also, any way to lower the srt-6 more than 1.2-1.5 inches? Im looking at the pro kit but im really looking to get 1.6-1.8ish. I rather not cut the springs. Is the pad system any good. Thanks
