G37 Track Set Up. Oversteer Help.

street2soul

Before you go down the spring/damper rabbithole, consider this a try:

For the mid corner snap oversteer, it appears to me your roll center may be too low, if your car is lowered especially in the rear. Car is transitioning to a sudden snap at the grip threshold because your rear rolls too suddenly and is not controlled. You may need to raise back the rear ride height and it will most likely improve rear slip consistency and improve snap oversteer

To me, it appears that for T1 corner, the oversteer is coming from trail braking not bleeding off enough while you're at full lock. I'm sure if roll center is your issue, that is contributing it to the oversteer happening at full lock while you are trailing off the brakes

I'm hoping this isn't an issue, I haven't had time to check rear travel either though. The main reason I hope it's not the roll center going Infinite is that would mean I need to start swapping Coilovers.

While not completely averse to it, I'd like to try and stay with my current set up if at all possible. The rear is at the Coilovers max allowable height and only a .8" drop from factory height with a 9k spring rate.

Do you have true coilovers or the oem style in the rear?

9K rear spring seems in the right range if it is in the OEM bucket location with 10k front spring rate. If you have 9K rear springs in true coilover style, that is way too high to match the 10k front. But I assume you're already aware of that.

Yeah OEM divorced set up, for a true type the spring would probably closer to 6k.
