Now that the dust has settled from the 600 Speedweek, the hot topics the last few weeks in the 600 Micro ranks have been whether the U6SA should mandate a spec tire and should 600 Speedweek go to the U6SA 600 engine rules?   Microracing.com will be following these stories closely and will update everyone right here as soon as we hear anything.

To participate in the ongoing discussions about the above topics visit the U6SA forum.
