To install these roll center adjusters on your 8th Gen Civic (06 - 11), first, make sure your car is on a flat and stable surface. Remove the old bushings and components carefully. Then, install the new adjusters in place. It's a good idea to have a professional mechanic handle the installation if you're not experienced. When driving, you'll notice improved handling right away. As for maintenance, check the bushings regularly for wear and tear. If you see any signs of damage, replace them promptly. Keep the adjusters clean to ensure smooth operation. Remember, these adjusters are 10mm taller than stock, so be aware of this when driving on uneven roads or in tight spaces.
