I own a 1991 Z28, I lowered my car with HOTCHKIS 1 inch lowering springs and Bilsteins on all fours. Had the car aligned almost 10-15 times and three different places. But the tire wear is tremendously fast. My tires still had about half the treadwear left prior to installing the springs. 3 months after installation, tire wear on the inner and outer treads went to nothing. Currently have 1998 Z28 SS 17x9 inch wheels with brand new BFG's comp t/a zr's. Had them on for approximately 3 months now and starting to notice outer tire wear. Any suggestions on how to correct the problem? Thanks
