Just curious if you can get away with sportlines without casterchamber plates or bumpsteer. They are rated for 2 inch in the front and 1.8 in the back

 

Not usually, there will be some cases where some can but I would always do c/c's going that low specially when you have some nice tires and wheels it protects your investment. I had the sportlines and I did the c/c's about 1500 miles later and I didn;t have any issues and that was with my stock wheel.....
