Does anyone know what is the difference (if any) between CL brake rotors and 5 lug on a 991 GTS '15? There are plenty of after market ones (Sebro, Fremax, ATE, ), but it does not specify if they will fit a CL car. Thanks!

I was hoping to get some answers but I guess nobody knows

The hat is different for CL's than 5 lug configuration. Brembo, Giro & AP make rotors for CL's to to name a few. Also if I call recall correctly, the peg's have to be changed on the GTS CL as they are part of the rotor. Hope this helps.

I have put these rotors side-by-side, measured the opening, aligned the 5 holes, etc. There is no apparent difference.

The only manufacturer making 2 piece rotors for the 991 S/GTS is Giro Disc.
AP, Brembo and PFC have nothing to offer.
The hats between the 5 lug and the CL are the same-interchangeable.

350MM rears are also available from Giro Disc.

I'm tempted to create a new post about this BECAUSE I have just installed aftermarket brake rotors meant for the 5-lug version.. on the rear of my 991 GTS with CENTER LOCKS (CL) without any issues whatsoever. I bought Fremax (cheapest) just in case they do not fit and they fit perfectly even though they are apparently only for the 5-lug wheels. I assume that Sebro and other brands would also fit if the Fremax do. I understand that Giro Disc makes their rotors to fit universally on both variants of the wheels, but if there are two different part numbers from Porsche what is the difference between the CL and 5-lug discs for this car? I certainly do not see any and cannot understand why we should be limited to buying brake discs specific to CL wheels, which are offered only by Porsche or Giro Disc.
