The 8.49 and quicker 25.5 sfi spec absolutely does not apply to the Superstock class in general. People keep bringing up Bo Butner getting kicked out of the divisional at Indy in his comp car and trying to compare that somehow to superstock ah needing to upgrade. Butner went quicker than 7.50 not 8.50. His car needed to be upgraded from 25.5 to 25.2.
