    Lightbulb2005 STS brake rotors and pads

    Hello together,

    I'm Sammy from Germany and I bought a 05 STS.
    Right now I need to new rotors and brake pads front and rear,
    but when I search for the GM parts by number I get different suggestions:
    with or without heavy duty and with or without performance package.

    Can you help me with this?
    Which one is the right one and what is a performance package?

    It's a 3.6 RWD.

    Thanks a lot for your help.

    Re: Cadillac STS brake rotors and pads

    ...well, 05 -07 sigma-based euro export cadillac sts only got JE5 or J56...
    ...the "performance JE5" only for STS V6 3.6 (5-lug) and the heavy duty brembo-based "J56" only for the STS V8 4.6 (6-lug) (...and the STS-V)
    ...from 08 up things changed...and the export 3.6 Di could have J56 also...

    ...a little German...:
    ...mal eben auf Deutsch, da Du ja schreibst, Du kommst aus Deutschland...hast Du ein "Domestic", also US-Modell...oder ein reguläres Europa-Export-Modell?
    ...die 3.6L V6 STS Europa Export-Modelle der Modelljahre 2005 - 2007 erhielten immer die sogenannten, etwas stärkeren "Performance Bremsen und Beläge", der RPO Code ist "JE5" mit "JE2"-Performance Bremsbelägen...den RPO-Sticker mit den Optionscodes findest Du im Kofferraum unter der Ersatzrad-Abdeckung...erkennbar auch an den Radschrauben...es sind 5-Loch Scheiben und 17 Zoll oder optionale 18 Zoll Felgen...
    ...die Europa-Exporte der V8-motorisierten STS mit dem 4.6L Northstar erhielten, im Gegensatz zu US- und Kanada-Markt, immer die "großen" Bremsen...ein Brembo-System...erkennbar an den noch größeren 6-Loch Bremsscheiben und Felgen, die hier immer 18 Zoll waren...der RPO-Code lautet "J56"...entsprechend anders und stärker sind auch dort die Bremssättel...
    ...die Basis-Bremsen, "JL9" gabs für den Europa-Export gar nicht...für den US-Markt allerdings war der 4.6L anfangs nur mit JL9 und den etwas größeren JL5 erhältlich...die große Option "J56" wurde dort erst später optional....zunächst war es dort nur dem STS-V vorbehalten...
    ...ab 2008 gabs wieder Änderungen für den V6...er wurde leistungsstärker und war, zumindest für den britischen Markt, da auch mit den großen "J56" ausgerüstet...über andere Märkte fehlen mir da aber auch noch genauere Infos...

    My bets on JE5. Nice setup.

    Good luck Sammy. I don't know your parts availability but over here, many members like Hawks.

    I just bought some rotors from brakeworld.com but trying to find Hawk brakes, they always have JE5 fronts but the rear are in JL9 (a lot of sites where like that)? I ended up picking up another brand
