My car is 100% stock for now. Size is 225/45/17 on RPF1.
Second question: The only thing I can play with to influence under/oversteer is tire pressure. On my RSX I would adjust the front pressure to have max grip without rolling on the side, and adjust the rear tire to remove some traction to have less understeer. I'm guessing the same apply for the BRZ; play with the rear pressure.
But on my RSX I found something strange. On my RS3 tires, I had to increase pressure to remove grip in the rear, but with the Dunlop Direzza ZII, that didn't work, instead I had to decrease pressure to remove grip in the rear.
How do the RE71 behave? Do I have to increase or decrease rear pressure to induce oversteer? Right now with the OEM tire I have good balance on corner entry, but understeer mid-corner, and sometimes also in exit.
Thanks

Hi Nico,
I would start out at around 32 hot in the front and 28 in the rear. If you want to loosen up the car, add rear tire pressure. I've been as high as 60psi in the rear on the RE71R to make a DS WRX turn
You will probably find yourself a bit loose though and for that, you really need a bigger front sway bar.
