I am looking for some help with shock settings and tire pressures for my 2013 Boss. I am still fairly new to autocrossing and have been running the same Rivals for the past 2 years. I was trying to make them last for as long as I could just to eliminate a variable while I learned. At the event last month 2 of them started showing cord so I replaced them with RT 660’s and ran my first event on them today. I was expecting to immediately pick up time and found myself frustrated all day long. I felt like I was fighting the car. I know one element I was simply over driver it as it looked like a fast section but there was very little grip in that section of the parking lot and I failed to adjust for it. The rest of the course I felt like I would have been faster on the Rivals, but they are familiar to me.
I am currently running pedders coilovers, 450lb front springs and 275 rear. They are 30 way adjustable and currently I am 15 on fronts and 7 from full soft on rear. I have white line sway bars which have 4 adjustment holes, I am 3rd hole from full stiff on front and softest setting on rear. I have all BMR spherical control arms in the back, middle hole on relocation bracket. Car was set for autocross by a local shop who took care of proper antisquat settings in the rear and -3 degrees camber in the front with .060 of toe out. Car has no aero on it.
I normally finish 2nd or 3rd over all at my local autocrosses and today found myself mid pack. I am thinking of putting stock upper control arm back on as some have suggested on these forums. Wondering if I should be much stiffer on shock settings with spring rates I have. I started out at 34psi front and 32 rear. I slowly came down to 31psi front and 30 rear. Tire wear was right at the triangles on the tread but no where near going over on the side wall. I thought these tires liked higher pressures but seemed like I could go lower if needed. Sorry for the long post, but any help would be greatly appreciated.
