928 S4 Front brake rotor upgrade to GTS size
Hi guys,
My 928 S4 front brake rotors need to be replaced. They have the 4 pot black Porsche callipers. I want to go up in disc diameter to match the GTS spec disc which is 322 mm . The S4 has a hat of 45 mm , 77mm form the far side with 103 hub bore on 5 x 130 PCD for the studs. The GTS discs 322 mm only seem available in Genuine Porsche, yet the 304mm you can purchase from Zimmerman or Sebro. I want to run the drilled discs with coating if possible. Ive heard the 965 (911-964 3.6 Turbo) 1-piece disc, cross drilled, 45mm top hat , part numbers- 965-351-045-00 965-351-046-00 They are the same ? and can be used .Pelican don’t list for Zimmerman , only Sebro for those part numbers. Appreciate any information. The car runs 17inch cup rims Pads to use for hard street- any thoughts – Pelican list Hawk for high performance. Maybe EBC red ? Again any information would be helpful |

My question is why? In street applications you brakes are plenty. GTS rotors are over $250ea. Drilling is just for looks. It removes surface area and is prone to cracking between holes with high heat. Also if you put on a larger rotor you will have to raise the caliper which would require a spacer of some kind and new bolts. It seems like a lot of headache for nothing.

Do a search on rennlist. Mark Kibort did something similar.

They were interchangeable in the Big Brake kit on my 951.

Check the Rennlist thread, lots of talk on the various options for unneeded brake upgrades.
