Using these coilover covers is easy. Just wrap them around your coilovers and use the Velcro and drawstrings to secure them in place. You don't have to remove the suspension to install them. Remember, they come in pairs, so if you have 4 coilovers, you'll need to buy two sets. In terms of maintenance, since they're made of waterproof material, you can simply wipe them clean with a damp cloth. Keep them in a dry place when not in use to prolong their lifespan.
