Using the BC Racing BR series coilovers for your Infiniti G35 AWD is a breeze. First, locate the easily accessible adjustment knobs to set your desired damping levels. You can make 30 different adjustments for compression and rebound to suit your driving conditions. To adjust the ride height, use the separate adjustment feature through the shock body. Remember, this adjustment is independent, so you can get that perfect look for your car. When it comes to maintenance, it's a good idea to check the coilovers regularly for any signs of wear or damage. Thanks to the 2 - year warranty, you're covered against manufacturer defects. If something goes wrong, don't worry as the coilovers are completely rebuildable, and you can buy individual parts separately. Just keep in mind that custom kits take a while to ship, up to 8+ weeks from the order date. Also, if you've got the optional rear extenders, use them to change the dampening range without the hassle of removing your rear seat every time.
