To be fair, if you might have read Jethro's article in EVO 299 about his track experience with the Emira, you would know that it managed a 1:18.5 time, which is decently fast. The Exige S did a 1:19.1, The F82 M4 1:19.2, the AMG GT S with 510 hp did a 1:17.0. Without a doubt the Emira would have been well below 1:17.0 with the Cup 2s. It would then be in Nissan GTR and Alfa Giulia GTAm territory, which is kind of a ridiculous achievement if you know the other cars and consider the Emira "only" has 400 hp.
Sadly they don't mention the Porsche Cayman GT4s time, not even in it's own article where it was compared to a tuned one. However they weighed the "super lightweight" Porsche: 1460 kg.
Am I the only one who finds these track times interesting? The Emira seems to hold its own among the top tier of "affordable" sports cars.
