I managed to get a challenge out of them at the ring. Custom Race in a stock Evo 96, added full weight, lowered power all the way, went down 1 tyre compound too. Started from the back of a grid of 20 cars. Slow car boost off, & everything set to as realistic as possible (no assists). They're still too slow around corners, but it was interesting to finally be able to get some kind of challenge out of them at least.
