Yeah, tyres wear down quickly and oil does need to be monitored.
Drive it like you want to slay the tyres and it will chew them up pretty quick, as they warm up, they wear down quicker. When it's hot and they're getting low, I do tend to leave the TCS on to make them last a bit longer.
I was managing about 8/9 laps of Brands before I was having to come in for a cool down but my tyres were going off well before the oil was reaching limp mode. It was 31 degrees that day though.
Oil cooler's are a common mod and I see big value in it, having to spend time in the pits letting your black cool down is a pain but overall its not too bad, as it not only cools the oil but the tyres and yourself also.
As a casual track day car it's fine as OEM really.
Apart from an ARK GRiP my car is OEM and it's an absolute joy, more grip than you think.
