Keep in mind that the traction ratings are for wet braking.

The tires fitted to at least SS-level and higher Camaros are good to something a lot closer to 0.9g. But let's be a little conservative and assume that in average hard use youo only achieve an 0.8g overall average rate of deceleration. 60^2 / (30 x 0.8) = 150 feet . . . which ought to "feel" a lot closer to your experience.


BTW, that stopdistinfo link is for dry braking (with nothing-special tires/brake system/pavement/driver).

Nice info!!
