Try lowering the pressure in the rear tires a little to around 40psi just for the traction benefit at the track. Use Sport+ mode with sport auto shifting. Make sure you are using the highest octane possible and only have a quarter or half a tank at the track to save weight. Take no passenger. Or buy a tune!!

"LOWERING" to 40psi?

What are they at as standard?

I keep my rears around 46psi warmish. I think standard is 42-44psi. Maybe I should have said <40psi.

No, my error, just looked at the handbook and for my 18" wheels it states 36front 42 rear. Not read this section yet, but I'm surprised at how hard they are. I'm used to my old MX-5 (Miata) that was about 26-29psi
