BIGGER 944 DISCS on Early Arms

Have ; 944T calipers running on thin na rotors at the rear.
Rear is aluminium caliper bracket on standard irs arm.
Am running the thin na disc minus the 21mm spacer.
Want to run thicker turbo size disc at rear.
Is there a disc that is a thick ventillated disc without spacer that would fit at the rear ??
Cheers
David
