Thinking about getting an SRA

[hw11]

I am a 22 year old, an entrepreneur, and a life long car lover. I have been doing track days since I turned 15 and, my first track car was a '92 miata, but now I have a 2015 Mustang Gt. Several weeks ago, I got the chance to drive a friend of mine's SRA. I plan on buying it from him in the near future, and needed some advice. He got the car from a friend a couple years ago, and has hardly driven it. I know that he has it on Hoosier R7s, but thats about all that I know about this car's consumables. I have worked on cars all of my life, and currently maintain a Mustang Gt, but was hoping you guys could provide me with some links, or recommendations for rotors, pads, oil, brake fluid, and anything else y'all can think of for a stock SRA. Also if you can give a general idea of the basic maintenance cost to run this car (track days only), I would greatly appreciate it (I assume it will cost quite a bit less than a Mustang)!

Thanks so much!
