So I just came from my a local auto x . Top time of the day was 40.088 courtesy of a supercharged or turbo charged miata... Any way I found it hard to run anything below 49 anytime I tapped the throttle the rear end would come out hard... I kept it sideways all over the place. In this location there is a lot of bumbs potholes and uneven pavement I wonder if that had anything to do with it. I wonder if it's time for rear shocks?? Or maybe it's just my Goodyear eagle F1 tires . Hot tire pressure was 35 front and 30 rear .. Any Input would be appreciated.
