996 mono's (blacks)

As you may know, my red porsche calipers are not the best there is. Also, I'm not satisfied with wheel spacers which I needed to use to fit 16" wheels. Current setup is machined Alfa Romeo 166 V6 discs (310x28) and 996 porsche GT3 rear calipers. Yes rear, so technically they are porsche 996 monoblocks, however I cannot call them so, because true 996 monoblocks are 996 NA front calipers :). I have them also, however was reluctant to fit, because it requires master brake cylinder replacement. Red setup is fine, fade resistant, however it does require to have hard foot. And I don't have one :(. To improve my speeds at the track, I need to focus on driving, not on braking. So black brake upgrade is under way. Also redrilled volvo S60 disks (305x28 directionaly vented BTW) will be used. This should fit 16" wheel without spacers (or with tiny one, not 2.5cm, like it is now).First measured all the distances, cut some templates from cardboard. Everything fits ok:
Then ordered batch of carriers at local machine shop. Design has some minor flaws (due to dramatic increases in machining price, I was forced to change initial design a bit), however virtual testing on computer shows, that those design flaws should not affect service of the carrier. BTW, this is for racing use only, not for everyday street application (lowest FOS is around 4, for street you may need something around 10)Test mount on my rusty spare suspension leg. Fits like it should:Volvo disk fits ok, however after it is getting some surface rust, temperature expansion - it will scratch suspension leg. Notice line of rust on the brake disk. That's scratching on the bearing play. Leg will need some modification (shaving few mm) at one place, which looks some manufacturing option - place for thead when using larger brakes. Also lower ball joint is too close to the disc. Compromises, compromises... Hope I will solve them.

Will see how it will perform overall. First painting, then master cyl. replacement to 20v one, and after that I hope I will have real racing brakes ;).

Update for November

Like always, when the air gets cold, I'm getting sick. This year is no exception. Car is left alone in the garage, and I'm fighting with microworld :(.

So there are news for November:Got broken camera as a gift. Managed to fix it a bit, and now I have something slightly better pictures than mobile phone. Can make photos of dark areas (with flash), etc. Cool! :).

Also, taking pictures with flash, and high resolution - reveals all the imperfections, rust, etc. Which are even not noticeable when looking live. So you will see all crap and mistakes I've made. That's not so cool ;).Here are few samples:
