However, autocross setups seems to prefer a wider contact patch for low speed grip.

I think it all depends on the BBK
Just curious, have you ever used a wider tire/rim configuration at the same day and conditions, I can almost guarantee you that a 17x9" wheels and 235/40/17 NT01s would result in better lap times since my friends did that test with their Miatas and we all agreed on that ..keep in mind, Miatas generally put about 140-150 whp on dynojet
