The discs are Brembo disks that DaveB machined to make the "J" hooks. They are said to be really great both on the track and on the road.
My guess is that it is a potent disk since the design is used in motorsport:
Haven't fitted the brakes yet so all I say is based on someone else's experience.

Well guys, I managed to install all the pieces...
The brakes are now installed and bedded in. I am using stock Brembo Porsche pads and the brakes stop really great.
I have done the bedding just like Pagid says (90mph to 50mph and 110mph to 50mph sessions) and the brakes stop incredibly well. The bedding in was done on a highway. I traveled for 40miles and 20 miles the road was wet (raining) and the other 20 miles the road was dry. The brakes and the tires never let me down. During my tests I never had the slightest fear that I will loose control (a great plus to Goodyear Eagle F1 Assymetric, I had the chance to test them on the wet previously but I am still amassed) and the stopping was incredible. I never got sick behind the steering well before these tests :driver:
The 17 inch OEM Goal rims (7,5x17 ET50) barely fit the Porsche brakes. The space between the caliper and the rim spokes is less than 1mm. This is not safe. I am considering selling these rims (this is a pity because I really like these rims and they really look nice with the Porsche calipers) or installing a 10mm hubcentric spacer. Any ideas?
The 16 inch winter rims fit behind the Porsche brakes but need 20mm spacers (per side). The rims would normally only need 10mm of spacers but then the caliper does not clear the rim radially. I am hoping that 1-2mm is enough between the caliper and the rim (radially). Any thoughts are welcome.
About the TT arms I can't say much... I will be able to make a review after a track day. What I feel now is that I lost a little bit on the "feel" of the car but I gained some more stability. My current settings are 2.15' negative camber and 0.04' toe out/per wheel.
The TT bushings are a killer on the roads I am traveling. Much to rough for my taste.
I got to test the car with a massive 6 degrees ToeOut and the car is was not driveable.
The setup below is just after I fitted the TT arms and before I made the geometry adjustments.
Any thoughts are welcome.
Cheers!

1.
fine brakes, Rex !! :congrats:
2.
Why toe out, Rex ???
I'd recommend 0°10' toe in per side on front and 0°5 on rear !!
3.
I don't felt any harshness when fittig S3 arms and bushings.

1.Thanks
2. From my studies and experience I will reduce the understeer if I use toe out for the front. I will use toe in for the back just like you said (that is how it is currently).
3. Maybe the roads you are riding are better.
the bruce:
I know it's difficult beause everybody tells something different. ;)
I don't believe toe out on front will help, but maybe I'll give it a try again.
Usually more toe in improves initially turn in and in case of the Golf cornering grip as well.
On rear toe out helps turn in, no doubt. But be careful, at high speeds toe out on rear
may cause dangerous situations. I never would adjust toe out on rear for street use.
ps:
no, roads here are the worst I know in Germany :wink:
