How do you fit this combination? The 993 TT rotors have a different offset and normally need aluminum hats to fit on the 944. I run the 911 C2 3.6 Turbo drilled 1-piece rotors on my car, which also has M030 steering knuckles and hubs.

BTW, the 5/33 brake bias valve, p/n 928 355 305 02 sure has gone up in price. The one I have in the S2 was $55 in 1999 and the one I just purchased for the 951 was $241!

^^Yikes.
The correct brake adapter kit is sold by Jason at Paragon Parts:
The 928GTS (1992-95 oem) Big black brakes have their lines oriented
to the correct side vs going with the 993 calipers.
But the cross drilled 993 rotors are probably superior to the solid rotors
for avoiding warpage.
You can get discount Zimmerman rotors, and you can get them drilled.
but i forget the vendor (928 Motorsports + Jason at Paragon??).
quick vendor reference list on page 1 of my build thread.

The Racer's Edge brake adapters for non M030 on Jason's site only work with stock offset rotors, not the 993 TT. The C2 3.6 Turbo rotors are also broached like the 993 TT. Big Blacks are also less expensive than Big Reds, but now there is an aftermarket Big Red clone for much less money, but I don't know anything about them.

I know Squire retired, but I wonder if his shop still does the V8 conversions as that might be an option for my 951 in the future.

That's quite odd, as i believe i'm running some humongous
cross drilled rotors with that kit.
Had the oem 928GT solid discs from 2010 to 2017.
Then put cross drilled rotors on.

So, do you have 2-piece or 1-piece rotors? Mine are 1-piece 965-351-045-00/965-351-046-00, which are the "drilled" equivalent of the GTS "non-drilled" rotors.

Not remotely sure. and i don't have the parts receipts in front of me.
I'm a coupl'a thousand miles away from the car. i'm in Glenwood Springs, CO.
Car is back at the house in Mass.
4 years on, i don't remember where i got the rotors.
Who drills out 928GT rotors? Definitely running 322mm. That must be what i have on there.

Awesome country! (I grew up in Glenwood Springs. Did you go to the hot springs pool?)
