A little too much discounting of drivers in this discussion, but agree that with equal drivers, the 1LE would absolutely annihilate a stock, or even not so stock, RX8.
Back to the driver thing though, I haven't watched it in a while, but there was a great video on YouTube of Doug Hayashi (of NSX-Files fame) in his relatively stock Honda S2000 (only mods were tires and pads IIRC) just walking away from a Ferrari 355, a 360 Challenge Stradale, and he would catch an F50 in the twisty bits but lose him on the banking (believe this was a track day at California Motor Speedway in the SportsCar configuration).
I just Googled the video but can't find it, here's something I did find though, an S2000 being held up continuously by a couple of 360 Challenge Stradales:
It's the driver more than the car.
