I've owned my 2012 SR5 since Feb 14. First thing I did was upgrade the interior lights, backup lights and license plate light to LED. The next thing I did was add the mats to all the storage areas so stuff wouldn't rattle and slide around. After this I just kept on spending, AVS low profile bug guard on the hood, TRD CAI, Sprint Booster, then the 5100s with the front set at .85. Wheels and tires are next!
