    Default Upgrade / Big Brake Conversion

    Hello All,

    Just checked my brakes and have noticed they are quite worn. Time to upgrade me thinks!

    Can anyone recommend me a decent brake upgrade? I was looking at AP racing but they only list the Vec B upgrades.

    I've got 17" pre facelift SRi wheels.

    You could fit the vxr 345mm brakes.
    Now I need a turbo to keep up!

    If you do a search there is loads of reading on the Vec C brake upgrade options. Assuming you have 285mm fronts there are 302mm (earler GSi), 314mm (later GSi and 2.8 V6) and 345mm (VXR) iirc. I have 314mm fronts with 292mm rear (V6 and VXR) and find them more than adaquet.
    These are brakes when I painted them.......

    The 314mm front caliper is pretty big and exactly the same size as the 345mm VXR front caliper but unfotunately pad fitment is slightly different.

    I have upgraded mine from 285mm to 314mm. The difference is amazing. Did the same on my old 2.0T (upgrading from 302 mm to 314mm and that made a big difference...but upgrading from 285mm to 314mm is something else).

    However 314mm brakes may not fit if you have 16" wheels. If you have 17" or bigger, then just do it. Braking quickly at motorway speeds with 285's is no laughing matter.

    I run 345mm setup with police spec pads from the 314mm setup
    also you can fit 314mm setup under 16's
    345mm need 17's

    how much do you want to spend on a brake kit ?

    ap's your looking at around £1500
    314mm about £300 if your near essex I have my old v6 314mm setup
    I could dig out for you

    345mm about £600 under a 17


    its all about what you want to spend I have had 314 on my vectra 1,9
    changed to 345mm
    sold the vectra so i fitted the kit to my zafira
    £ for £ the 314 kit was the best upgrade of the lot
