C & B classes :
Drag : RS4 .
Races :Solstice / M3 E30 / RX-8s
The Miura may handle great but it's slow in B class .
The Ford GT doesn't even handle great , it's good only for B class highspeed tracks .
By Lotus you must mean Lotus Exige - same thing as Miura , very good handling but lacks acceleration.
By these that you mentioned Miura and Exige are better options than Ford GT .
