Mike,
More will come in street cars. This one got applied to the track car for many reasons.

We have lots of time, we won't be seeing the majority of these cars equipped with the larger diameter bearing for 2-3 more years.

The larger diameter bearing responds to engine RPM differently.

It is more difficult to carry out development and check up on the larger diameter bearing, since it can't be removed without complete teardown..

At the present, if we update an MY 06 or newer engine, we back date the IMS and use the triple row IMS update, something thats proven.
