So far just autocross, no actual track time yet. We did an autocross “test” day last year, that gives you all day to test things. I ran the track several times running very consistent times. I pulled the rear sway bar and ran a few times. I was consistently a half of a second slower without the sway bar. Reinstalled the sway bar and my times dropped back to where it was before.
even if there was no time difference, the car felt a lot better with a sway bar than without. On the street, you’ll probably never notice a difference.
When I do get a chance to track the goblin, I will run the same experiment
