Also...If you take you Mustang out of stock class you will likely never be very competitive with the other cars in you class...not that they are very competitive in stock class. (If you care to be.) Best bet is stay in stock class and do the minimal chages your allowed...tires, cat back, air filter, etc... If you get a good set of Hoosier autocross tires that will be the best thing for your car. Then build your skills up and attend a couple driver training classes at Mid-Ohio or like places.
However...if you already have engine mods you need to see what class that will put you in. Which anything major will put you in the "Prepared" class which is for all out race cars. Minimum mods are aloud to run in "Street Prepared" but you will need to get a 2010 SCCA rules book to know what those are...they have probably changed since I was active in it.
I ran a Mustang '86 GT, '90 GT, and a '03 GT for several years. They are fun but will never handle as good as a Camaro or some of the other cars in the same class...sad fact. The most competitive car I ever raced was our 1973 Datsun 240Z's.
