WTC600 Interlagos Suggestions?

What car did you use for the WTC600? I’ve tried so many combinations and I always find I finish about 3-4 seconds behind 1st every time. Best I could do was 2nd but the Huracan was impossible to catch.

I’ve tried ‘19 Supra RZ, Amemita RX7, Corvette Gr.3 Road Car, Alpine VGT and ‘24 GTR so far. Any suggestions so I don’t waste another 10 mins
