    Brake upgrade ?

    Has anyone been looking or have informations about brake upgrades for the A3 8V ?

    What can we mount from other cars, any brake kit available ?

    Are brakes from Golf golf 5 R32, S3 8P etc possible to mount ?

    I think the 8V S3 brakes are different from the 8P S3 brakes, well they feel different when using them hard.

    Im running approx 330 bhp and I have never felt the need to upgrade brakes. A friend running approx 360 feels the same. Others on here think its a worthwhile upgrade. I think you just need to ask yourself why you feel you need to upgrade? Have you been in a situation where you thought, God I need better brakes?

    Well clearly there were no situation when I felt I just almost died because the brakes were ****. mind you they are already 312 x 25 (as you know S3 8P brakes are 345 x 30.) and I didn't have the occasions to push them really hard.

    Still when I had my S3 8L wich had almost the same setup : (discs were 312 x 25 and maybe even the calipers are the same) Car was about the same weight, had a bit more power, so I think it's a good point of comparison
    I warped the discs without any trackday on a simple mountain road with the S3
    then I went bigger and loved it !



    I also have at the moment a Lotus Elise 111R which I actually don't use much but the brakes are nice !


    Then, do I really need S3 brakes ? Not really
    maybe until I go to some trackdays wich I will probably will but not before I swap my winter tires.

    I was interested in big brake kit but it may be a bit overkill, and I don't want to spend 1500£ on this car for the brakes.

    Then again, bigger brakes look nice on 18" wheels

    well to keep this post up to date I searched a lot about brake weight and those are my discoveries :

    S3 345 brakes : calipers : 8,5kg discs : 12 total 20,5
    A3 312 : calipers : 6kg discs : 8,6kg total 14,6
    TTRS : total 17Kg
    S3 340 : total : 20
    VW racing 352*32 : 12

    A3 312 + Boxter calipers : calipers : 3,6kg discs : 8,6 total : 12,2


    At first I was interested by S3 345 brakes because of the OEM look, but they are way too heavy and I'm not sure it represents a huge improvement.

    Then TTRS brakes because they are cheap to buy but it seems they are a pain in the a*s to fit: need spacer, won't fit every 18" rims etc and parts are hugely expensive !! (500£ for 2 discs and 300£ for pads)

    Now I am looking at the porsche boxter (non S) front calipers conversion.

    Good things are :
    - WEIGHT !! calipers are 2,4kg lighter than the A3 calipers and 5Kg ligher than S3 calipers PER SIDE !!
    - COST : boxter calipers are really cheap, I found 2 with pads (used) for around 300£ with shipping.
    - COST again : no need to change the discs, they are just plug and play. and therefore, discs will still be cheap when you need to change them !

    All you need is :

    boxter non-S FRONT calipers (parts : 986.351.421, 986.351.422)
    Brackets to fit the calipers
    hoses with the correct end for porsche calipers

    then you have this :
