Using your BC Racing BR series coilovers is straightforward. First, install the coilovers according to the included instructions. Adjust the ride height by using the accessible adjustment knobs to get the look and performance you want. You can also fine - tune the damping with 30 levels of adjustment for compression and rebound. When it comes to maintenance, regularly check the coilovers for any signs of damage or leaks. If you notice anything unusual, it's a good idea to have them inspected. The coilovers are completely rebuildable, and individual parts can be bought separately. Remember, custom kits take time to ship, so plan ahead. And if you choose to use the optional rear extenders, they'll make changing the dampening range easier without the hassle of removing the rear seat every time.
