323mm under 16s

PNs for Big Reds/Blacks on NAmerican C4 UrS4/S6 struts

What part numbers are the 928 calipers? Are they the 2 piece 993 items? There was very little chance of fitting my current 996 calipers under the Avus with a 4.5mm spacing. With a 3mm spacing, it will be very tight but the chances of massive brake temperatures while running those wheels are low...

Remember that I am talking C4 not B3 or B4 and also North American C4 UrS4/S6 which got different wheel bearing carriers than either the Euro/ROW C4 UrS4/S6s that came with UFOs or the HP2s. With that as context, the PNs that work for us in North America are:

RS2 BRACKETS
8A0 615 125 A (034Motorsports or VAG Parts) (or Apikol clones)

993tt Big Red Calipers:
993-351-425-10 (left), 993-351-426-10 (right)

Porsche 928 GTS front calipers
Porsche P/N -928-351-423-03 L, 928-351-424-03 R

Later A8 ROTORS (323x30, 5/112) (early D2 S8 rotors)
4D0 615 301 A or J (A was superceded by J)

Also:
Bolts, long (caliper to bracket, x4)
999.067.041.09

Bolt, short (Strut to bracket, x4)
N 100 880 03
Bolt size is: M12x1.25x25mm

Vibration dampers 44 mm (x4)
965 351 096 00

Vibration dampers 36 mm (x4)
964 351 096 01

Wear Sensors (x2)
993.612.368.00

Wear Sensor holders (x2)
928.612.361.00

Brake lines (x2)
443 611 707 C (rubber OEM, M-F, 405 mm long)
Or custom stainless steel

Those calipers must be smaller than the 996 or at least a different cross section. Will see how they go with 3mm spacers to allow some 321s.

I did a conversion to 314mm disc's with porsche monoblocks under 16inch avus wheels about 8 years ago, at the time I remember it being a very close fit but was told that this was normal. I've just removed the discs today and they measure 323 x 30mm and have cooling vents facing inwards.

OOps! Who is to blame for that?

I'm not sure really but I remember being told at the time that 314mm was the biggest you can go under avus 16's.

I'm using the set up Dave referenced in post #16 above on a UrS6 with stock Avus wheels with zero fitment issues. (993tt calipers, D2 A8 rotors, RS2 carriers). Since 2005.

They lied.

A8(D2) 323 with RS2 calipers do fit under 16" Avus MkI.

If the rs2 brembo are a 2 peice bolted design then I wouldn't think there was enough room, the mono blocks only just fit with a couple of mm spare.
