BC are sweet. I have them in my car. I love how well the shock adjustability works. You can really notice the stiffness when you go from soft to medium to hard. I believe it's 32-way adjustable. Soft will give you a nice stock like feel. It will ride nice and smooth on city roads. Bump it up to medium and the car is ready to be thorn whatever you want at it lol. I haven't gone to full hard yet.
Bullet ride is right when he says that an average DIYer can't install these. I had mine installed by stance factory. They did a great job. I also purchased the BC coils off them. Contact stance factory for more info.
