I suppose that's why Porsche is continually upgrading the brakes on all its cars... There were at least 4 upgrades over the 928's production run.

There's more to braking than being able to "lock up the tires." Hell, even drum brakes will "lock up the tires" - at least once before they fade to nothing. There is also brake feel, control, and yes, heat management. Upgrading to S4 or better brakes is one of the most worthwhile improvements you can make on an early car - whether you drive it on the track or not.

There is nothing particularly bad about the brakes on the early cars, the 4 piston Brembos just work better.
