    Are VXR Front and Rear discs and pads larger than on other models?

    As above - wondering whether it is worth upgrading to a VXR breaking setup on a 1.9 150bhp model or not?

    Cheers guys!

    I have on my coupe and would say yes it is.
    Tell me what you've done, not what you're going to!

    Are both the front and rears larger? Or just the fronts? I had a look at a local vaux dealer, and it looked like the rears were the same size...

    The fronts on the 1.9 are 308mm, the vxr's are 322mm.

    ZS on here has upgraded his fronts to vxr brakes so best to ask him if he thinks it is worth it or not.

    Not sure on the rears.

    Fronts use bigger discs and carriers, calipers and pads are the same.

    Rears are the same.

    Is it worth bothering with an upgrade then on the fronts? Or am I just better off getting higher performance discs and pads of the existing size?

    changed the front disks and calipers on my Zafrira GSi from a knackered set of 308mm to a new VXR 322mm setup and found no difference at all. I would personally say do not bother but maybe change the 308mm disks for better ones and retain the OE pads
    Be Happy

    Right then - new plan is to clean the existing set of brake bits on the car and paint what can be painted to make them look a little nicer. New pads and discs are going to be bought shortly, performance ones being prefered, any suggestions welcome!

    Dear God, yes. Every Astra should have anchors like the VXR setup.

    When they went on first they felt pants, spongy pedal, and not much more braking than my worn out 308s. Took 1500 miles before they bedded in properly, now you need to be careful braking on motorways incase someone ends up your chuff.

    Consider the 322mm Astra front discs are 8mm wider than Vectra VXR front brakes, which are designed for 155mph stops. Sort of tells you what they're like.

    They fit under standard 17" rims with at least 10mm to spare between the caliper and rim. In total my complete VXR front setup cost less than £500 (brackets were used ones, calipers, pads, discs, and the hoses were all new).

    I suspect jalfrezigee didn't bed his in properly, or hasn't given them time to bed in right. Mine got a baptism of fire (there was literally smoke coming out of them an hour after fitting!)
