Do the MPSSs need to be warmed up before they'll grip on the road? I have them inflated to 37psi. I haven't tracked them so it's not like they were heat cycled. Baffled...

Basically, 37 psi is high for this tire in this size on this car. If you heat up the tires the tire pressure effects will be worse, not better. Having tire pressures too high front and rear will not be the cause of your problem. At low speeds in tight corners under hard acceleration with traction control off you will oversteer. Period.
