To some extent it depends on your plans with the tires and why the (possibly) difference in opinions.

If you are talking street driving and not pushing the car, the change in grip from the tires heating up should not really be an issue. If you are doing anything that pushes the tires (track days, autocross, or spirited street/canyon driving), then the rate of the tires heating up certainly does matter and one should be very careful about mixing tires.

Simply put, you can have a situation where one end gets better grip than the other which will cause understeer (if it the rear gripping better) or oversteer (if it is the front). Oversteer specially can be problematic on this car if you drive near 10/10ths.
