Maybe you should go to events that have skilled drivers. At the last sunriders event 2 cars stuck out. First was the v6 stalker and second was a bone stock neon acr on victoracers. The stalker beat the acr by roughly .1 sec, and had azenis, which the sunriders course favors. Anyway both of those cars were 3-4 sec ahead of the closest competitor on a 42 sec course which as you know is a huge difference. Friend in stock 97 gsr could only manage a 50 on bfg comp tas, full slicks.

Edit: There were also several heavily modified wrxs that were running something like 47 sec.
