944T calipers on NA spindles?

Mike, sorry to disagree, but the hubs are not the same. Yes it's true the discs are thicker but to compensate for that Porsche made the Turbo's hubs thinner than the N/A.

In short...

thick hub/thin disc = N/A
thick disc/thin hub = Turbo

Reading many experiences (on a 944/951 forum) from Porsche owners I've learned this type of mixture of the Turbo and N/A parts is next to impossible to make work correct. Some that have gotten the calipers mounted with custom brackets reported problems that the Turbo calipers would crack the thin N/A discs. In the end the conclusion and what ended up working for a few were Boxster monobloc calipers on N/A brakes. The Boxster discs are more the size of the N/A for better fitment.
