Just thought I'd share since I've had the springs for about 2-3 years now, been about 40K miles. Got the tires a few months back so I thought I'd get an alignment. I had the Firestone unlimited but the person at my local Firestone was a complete d*** when I told him to toe in my front tires. He ended up giving me a refund so I went to the dealership and told them to try to toe the front in a little bit, they got it to 0.04 on both sides. My alignment wasn't really bad from the start but I felt like I hit a few potholes and felt like I needed it, they were running a special for $160-170. Car is driving really good, not sure if it's a placebo but feel like it's almost better. The car is also on 19x9 +30 wheels all around.
