I would save yourself a few bucks and go with the SportContact 3's. They are still very good tires.
I am leaning towards the SC3s. A little cheaper and a little longer lasting for 90-95% of the PS2's performance. I definitely consider myself a novice performance driver. My "performance" car experience is comprised of driving/owning a Lexus GS430 for two years and then afterwards my current 335xi for the last year.
I never tracked before so for the first set of tires I almost certainly won't be able to take advantage of that slightly better margin of grip the PS2 offers. I definitely plan on taking advantage of the M3's capability by enrolling in a perfomance driving school and then doing some track days though.
For these 19" tires though, I want a more liveable ride/low noise since this will be my DD and I plan on taking some long road trips. The more I think about it, the more a seperate set of 18" track tires make sense to me.
Do you think the SportContact 3s on 19s will be trackable tires or should I specialize and stick with the oem 18s as my dedicated track tires? What about the SportContact 2s? I can save about $370 getting those (abet with the rears being 10mm wider and slightly taller) but if they are significantly noiser/more prone to hydroplanning vs the SC3s the savings is not worth the penalty.
