Changing the floating front discs took longer time than expected, but now its done. Here is some pictures of my ti' with
vented rear discs:
The full brake spec of my car then becomes:

Bias: The bias, using AP Racing w. 330x28mm discs up front, is slightly moved rearwards. Stock bias is 66.59% and my configuration ends on 64.68%.
Weight: My vented rear configuration is 1kg (2.2lbs) heavier pr. wheel than the stock configuration. That is 2 kg in addition on the rear axle. Compared to the replaced e34 m5 rear caliper previously used, the new rear configuration is 600g heavier pr. wheel...
The front BBK is 2.9kg pr. wheel
lighter than the stock 323ti brakes.
Comparing my BBK with stock shows that in
total my custom BBK is 3.8kg
lighter than the stock 323ti/318ti configuration.
Stopping distance: Theoretically the stopping distance is 37.2m. The result from my road test runs show a stopping distance of 37.28m in average (100-0km/h). The best was 36.59m and the worst was 37.64m. Peak g was 1.1 m^2/sec.

Miscellaneous: Discovered that there exist a brake upgrade option for the TVR Cerbera using the same AP Racing calipers front and rear as in my kit. The rumor is that AP was involved in that development. The Cerbera's has between 355 and 426hp, weighing between 1100 and 1200kg...
