    dont get boxter-s rear or 993 rears.. you will have a very bad brake pedal and no gains only losses in braking

    you have been warned

    I found this quote

    Drew no need to get wet in this weather, 2.5 and 2.7 (986) Boxster calipers are dimensionally the same front and rear, they also share this caliper with the 996 Carrera rear. Boxster Calipers on 2.5's and 2.7's are a matt black anodised finish
    The 986S (Boxster S) has the same setup as a 996 Carrera 2/4 Boxster S calipers are Red,..... 996 Calipers are Painted Gloss Black or Silver as an option.
    Buyer beware boxster rears 986.352.421 & 422 are configured for a 20mm disc and you cannot physically get this caliper over the top of a 25mm wide VAG 312 Disc. The difference ison the pad pegs, they extend further out onthe rears to fit the thinner discs
    In summary
    Boxster (2.5 & 2.7) Fronts - All Good (Need reversing though)
    Boxster (2.5 & 2.7) Rears - No Good for VAG
    Boxster S & Carrera 2/4 Fronts (and also 996 Twin Turbo rears) - Good for VAG on custom 330mm discs - search Rays (aRd)'s posts
    Boxster S rears - Good for VAG dont need reversing
    996 Carrera 2/4 Rears - Good for VAG dont need reversing
    The calipers that DO need reversing have larger pistons, some see these bigger pistons as a benefit for ultimate stopping power with racing pads on a track. For fast street the smaller pistoned calipers all give forehead against windscreen performance with an absolute solid pedal because smaller pistons need less pedal travel which is Hydraulics 101!

    they do not mention at any point the piston sizes of these, which is what will give you very poor firm pedal and worse than std brakes if you choose them incorrectly

    buyer beware

    What correct size i need?
    If i understand you
    porsche boxster s rear calipper - Not good (poor pedal)
    porsche boxster rear calipper (986.352.421 & 422) - good (normal pedal)
    Porsche 986 Front calipers:996-351-425-11-OEM 996-351-426-11-OEM - good (nnormal pedal)

    Or I can buy 100% copy of a AP Racing made in russia (~1200$) [​IMG]

    Or the last - Don`t modify anything, and use stock Audi S3 calipers?

    Give me advice plz =)
