brakes for series one

ive had a look at a few past threads regarding this,my rear brakes are massive compaired to the fronts which are standard size but grooved so time for a brake upgrade.ive read about the conversion and whats required ie 11mm spacers but has anybody got pics of the setup and how it goes on the car?

any prices to the conversion and also are speacial brake pipes req?ive got a set of goodridge hoses on at the moment.

also are there performance discs avaliable for the st170 groved etc and again prices.
