Here's a not so subtle hint...
Here's it in action...
And here's me barely missing it's time.
CLK63BS is Superstock whereas the SLK55 is A stock. However, I'd like to add that my times progressively got better and I never hit a cone. Cone hits are indicated by the (X number.
So, the 63 got a 43.866 vs my 55 at 44.048. That's a .182 difference.
Overall, I'm quite happy with my results especially considering that nearly every other A stock (at least all that beat me) had sticky race slicks with wear ratings of 40 compared to my street tires with a wear rating of 200.
