Measured the caliper and wheel's today on their own:

15.5lbs for the caliper

26.4lbs for the BBS forged wheel at 19x9.........


.....dissapointed?

Disappointed?...no.

Brakes really are all about mass. Mass is what tempers peak temperatures. Design facilitates quicker heat dissipation.

And the wheels...they seem to be about the midpoint to what most other 19x9 wheels weigh. And these are OEM wheels which have higher abuse standards to live up to which certainly justifies the added 3-4lbs above a "tuner" wheel.

Unsprung weight performance is relative to the cars weight. The IS-F is no featherweight so its absolute unsprung mass shouldn't be compared relative to say a miata. I'm sure they are using plenty of aluminum components in the suspension no?

Thanks for finding out this info though!
