    I have a question about a brake disc upgrade/conversion -

    I have a pair of (from my old car):

    EBC Brakes RENAULT Twingo 1.2 Turbo EBC Turbo Grooved Front Brake Discs - GD572
    Twingo 1.2 Turbo
    This is a Vented 4 Stud Brake Disc
    Brake Disc Dimensions:
    Diameter: 259mm
    Height: 41mm
    Thickness (new/min): 21/19mm.

    Would the above fit a Copen or am I just wasting my time?

    (Copen for comparison)

    EBC Brakes DAIHATSU Copen 1.3 EBC Standard Front Brake Discs - D1620
    Copen 1.3
    This is a Vented 4 Stud Brake Disc
    Brake Disc Dimensions:
    Diameter: 246mm
    Height: 42mm
    Thickness (new/min): 17/15mm.

    The Diameter and Thickness are a lot different but the Height is almost identical. Any thoughts? It would be a shame to waste them as I am past the date I could send them back to the shop. I have standard wheels on and calipers.

    Cheers,

    Quartz.

    I imagine standard calipers would not fit the wider disk. These are nearly 1½ cm greater radius which i would say would foul the calipers, if you could even get them back on to line up with the mounting holes. Go look at the brakes, is there a 1½ cm gap in the caliper body? if not, then = won't fit. Plus as I said the extra width, you'd need almost half worn brake pads to fit in!

    Just my thoughts

    Best not mess with the brakes unless you really know what you are doing.

    I realised afterwards I made an error, the gap would be half the difference in diameter, its the difference in radius So would approx ¾ cm extra still fit in the caliper?

    Listen to DaG, he doesn't like messing with his brakes that much he doesn't even use the brake pedal!

    Doing work on the brakes is fine, changing pads, shoes, discs, etc. However transplanting something onto a car that wasn't made for it is a different ball game especially taking into account the dimension differences.

    Just a thought really. They are larger like but I wasn't sure without actually trying, wasn't so sure if a 13 mm greater diameter would make much difference when it comes to the curvature of the disc meeting caliper.

    There is usually a thin metal stone guard attached to the hub which wraps itself around the disc. This might foul a larger disc diameter though you could probably alter it.
