Only one mistake you have mention Downforce setting on your tune but you have not mention a Wing, I have added one to the car, and also when you post a tune could you please mention what type of tyres you used when tunning the car up thanks and I have a review for you as well.
I use your Subaru BRZ S '12 for the
Intermediate Level Non-Race Car Challenge (500PP SH) and I won the race easy and also using my G29 wheel, the handling of the car is good on Sports Hard tyres, no major issues with your car and overall a good tune thank you
