    Yes, but 10kg off my fat ass and 10kg off my rotating unsprung weight would be a good situation no?

    Isn't unsprung weight multiplied by some silly factor to give the effective weight loss? Much easier than cutting down on beers :D

    dude just skim the fuk out of the discs, and even drill them on the face and the top hat bit if they have one. done it years ago saves bits of weight. bang a bike caliper or 2 on each wheel but id find some decent front calipers for piece of mind though.

    I'd not skim down a normal disc as they're cast shit. If it was bar stock turned to a disc then fair enough but cast is not very strong so don't fancy that.

    As for brakes, apart from pad area - a standard caliper is a 1-pot sliding/rusty P.O.S, so I wouldn't be surprised if a bike caliper has more clamping force than standard brakes anyway!

    i like the idea as long as it is safe rather than using bike disc id get some made for the job also you could run inboard rear brakes to reduce unsprung weight even more

    This will work, so long as your not on the middle pedal too much shifting weight. Please do this, I want to see how well and durable this turns out to be! Great outside the box thinking!

    Thanks for your support. I'll crack on with it. Have to buy the car first though ;)

    I can't take credit for the idea, it's just an extreme case of reducing weight. I've got several other ideas for my next car so we'll see how it work's out :D

    MJG is onto something with this. Even the fronts aren't used hard in comparison to a 'grip' track car. I have R33 GTR rear discs and calipers on my S14 and I still do the warm up laps dragging the handbrake to warm the brakes up.

    Thanks for deleting that sucker.

    Anyway I've been looking into this more, just waiting to win some motorbike calipers and discs from t'ebay so I can start jamming things together and scratching my head. Only issue is that I don't have my next car yet, and a lot of this BS plan hinges on having the stuff infront of me. I'll revive this thread from the dead when I have some progress.

    old post, but did you fit motorbike brakes in the end?

    I've seen rear brakes replaced in rallycross car and wondering how it's done.
