im fully stock with the longer lines, no lift with stock tires, i went out offroading with them and had no problems.. even got high centered once and a jeep in our group actually snagged a rear line on a rock while we were out. no problems for me, just make sure who ever does your installation ties them back well. the only issue i had was when my vx was at the dealership the mechanic there complained that they were too long and that he refused to touch them because they were aftermarket.
