I searched and didnt find anything.

I heard from somewhere that you can put a mx6 or something brake booster onto the fc. Im not sure what brake booster it was. but I just want to know if anyone has done it. or if anyonw knows of an upgrade.
anyway i was told it would make my brakes alot more stiff.

Im looking for a direct bolt-in. i dont really want to mess with cutting and rigging stuff.

I want to have my brake pedal (and clutch pedal) to be as stiff as i can get them. I want my leg to hurt after pushing the clutch in for 3 lights.

pm me any info. or ill try and remember to check this post.

 

Um, why?

A heavy clutch is not a good thing, unless you need 3X the torque capacity.

And to get stiffer brakes, you DON'T want a better brake booster (it will make them SOFTER), you want teflon brake lines or a different master cylinder.

 

+1 on the why a heavy clutch, or are you just masochistic? A heavy clutch pedal is a compromise that one grudgingly accepts to be able to put lots of power down without it slipping, not something that one should aspire to have. Besides, you'd need to have a stiffer pressure plate in order to stiffen it. A different MC will just make it run out of travel before the clutch is fully disengaged, or it'll try to push it too far, possibly damaging the whole assembly.

That gives a noticably firmer pedal and is highly reccomended. I'm pretty sure your friend meant brake master cylinder, not booster. Putting a larger MC on will increase the effort required. I hear that the 1" 929 MC fits on the S5 TII booster, but it may need some brake lines to be fabbed. You could also just unplug the vaccum source from the booster (cap the line) and figure out that it's now really hard to stop the car fast and then promptly put it back together.

 

This is equivalent to removing the PS belt to see what a manual rack might feel like...i.e., doesn't really tell you anything except that an intentionally disabled booster system makes for terrible braking.
It's certainly possible to remove the booster and fab in a twin MC/bias bar setup that would provide great feel and performance but that would hardly be the plug-n-play project the OP asked for.

I too am mystified about the desire for a clutch that is painful to use.
