stock are 12.5, so 11.5 would be an inch lower. how tall r u? you dont have to do the front but it is recomended to keep handling up. you could try the back first then do the front if your not happy. either way you should upgrade the fronts, best 55 bucks you can spend. easy to install to. do one side at a time and with a lil help you can do it in about 10min. just the 2 bolts and your all set.
