I have only run shorty config. Compared to my old 2013 car on wet astro it seems to have just as much grip, bit more rotation but I like a loose rear. Lap times seem up a little to, but I am less consistent so far. Surprised as was expecting shorty to bee better in high grip. I run shocks on the rear, which seems to help top. I am a middle of the road f3 driver though so you may want to take all of that with a pinch of salt
