Update. We made the big trip to the UK and back over the weekend for a trackday at Rockingham. Ran Toyo R888 on her for the first time and they completely take out the understeer in the car. They were superb on track.
They are however extremely noisy and was glad to take them off. The brakes are holding up very well considering the amount of track time this car has had. Had to clean the drilled discs as brake dust had settled in the holes. Did that with a wooden skewer. It was really caked in.
