1) Yes, unfortunately. The SPI GUI calculates the actual data rate for master or slave devices.
This can be found in the SPI component datasheet Slave data rate calculations section.
2) No. The maximum SCLK of SPI master powered at +1.8V and 48MHz HFCLK is 4MHz.

Regarding 1), as dogaru_liviu_2439176 mentioned, the answer is YES.
However regarding 2), according to the PSoC 4000S Architecture TRM section 14.2.9 Internally and Externally Clocked SPI Operations, the maximum bit rate is 12Mbps.
Thank you for your advice.
I could set 8Mbps in +1.8V and measued it with osilloscope.
