I can't quite get my head around how this works on a FB Tool...... FB front discs are part of the hub so how does this work?

Here's a link to the RESpeed kit:

http://rotarycarclub.com/rotary_forum/s ... 137&page=2

My discs unbolt off the back of the hub. You would have to put your hubs in a lathe or some such and cut the discs from the hub.

Then do as I did.

Thoughts anyone?

but the thickness of the disc where it sat on the face of the hub would mean the disc wouldn't align with the caliper, is that right? Plus it would affect the offset?
Plus anything that involves Respeed is a big no for me, there's no way I'd send them any money.
Would the larger brake setup fit inside the stock s3 wheel?

You're offset would change by 10mm, but that's 10mm more poke, which is what you want anyway.

You build your bracket to locate the caliper and then space it/shim it to sit over the disc. The FC disc gets it in the right place anyway.

You wouldn't buy from them now, but buying one off a forum would be ok. Keep an eye out.

Highly unlikey to fit under stock S3 wheels. If you're upgrading your brakes, you should be upgrading the wheels and tyres anyway, otherwise what's the point?

You can follow that link I posted and buy steel hubs. Then fit FC discs over the top.

Too much engineering. Machining brakes off, cutting brackets laser cut or order cross-continent from some shoddy and no longer existing company... Meh :roll: Hardly a DIY job, lol. TBH when FB brakes are in good nick they're quite able to lock the wheels, the only reason I thought about the upgrade is to improve the pedal feel but then you probably need to upgrade the master cylinder as well... then new lines, disc shields... etc etc. Too much work, I'd have to be doing a body-of resto to be arsed with all that :(

Still, thanks for the write-up, appreciate the effort!

Never too much of engineering to me and need more!...
look at my own work on wishbones,brake system , hub and bearings out from wee fiat car, Brake disc from Vw golf/ford fiesta and drill many holes. it did stop very well.
