Went to reputable performance shop for this.

They informed that the racing compounds (ATE blue, Castrol SRF) eroded the M3 brake lines over time. In order to counteract this, stainless steel lines would be required. If only tracking 1-3 times a year, they recommended the OEM fluid (which is what I went with for 120 or so).
