Hi,
You know, a set of sticky tires and ALKY might get you into the the low 13s, but 11s are another issue entirely.Don't believe everything you read. As the man said previously,paraphrased,of course,it is a hard fought war to improve your performance. With our cars, you will have to deal with a bunch of problems, but it will be rewarding, eventually. You should look at it as a chalenge. Good luck with this!
