[Brumos RSR]

For the GT3 proxy, I was told that it has basically become a tyre proxy...so as I don't have the opportunity to test and tune on wood, my entry is based on scientific theory and hope.

It’s a little more than just tires, for example I finished 11th in 2019 and with the same car , slower motor, new guide, original tires and 6 practice laps, I sent the car back in and missed finishing 5th by 2 points. My car was FAST but not easy to drive fast.  If it were tires everyone would run ultragrips on the car and send it or old NSR Extremes that have hardened slightly.   Having them round with a slightly round corner like Thunderslot tires, will get you to town.  Front end set up, ride height and weight placement are also key.
