Gentle suggestion:

Get to an AX, DE, or performance driving school and get an instructor in your car. After 6-8 weekends of performance driving with experienced instructors you will have a much better idea about what changes you do/do not need to make to your car. I generally recommend new drivers just get a set of quality street tires and drive the car bone stock the first year. Tighten the loose spacer behind the steering wheel first.

One of the best Performance driving schools in the country is being held in San Diego this October. Barber and Bondurant charge $2k for similar programs, PCA-SDR charges $350. It will transform your driving skills and I highly recommend it.
