I'm with 14ward. I have no issue with the current rules or tire. Really puts the driver into the equation, and the setup guy. I've seen a ton of really good IMCA races the last 2 years.... sometimes, yes, there are a lot of cautions.... but I've seen that in EVERY division from time to time. Only change I would like to see is more checked, more often, and equal enforcement of penalties. That last one isn't really much a problem (where tech is concerned), because not much gets checked (and that is my point). This all falls on the tracks though, not IMCA.
As I said before, I honestly don't feel it's a lack of effort or intent on the part of the tracks or their personnel (95% of the time anyway, there are exceptions), but rather a matter of a lack of manpower.
