BB1995S6

My car has big reds and I found the right pads they are off.a 2000 c4s but the rotors are a different story I tried 4d0615301j too big also tried 8e0615301j and they are the right diameter 12.25 but they are the wrong offset does anyone have a clue? Thanks again in advance mike

You are finding that "Big Reds" is not a very good description for a BBK. "Big Reds" is actually the name for 993tt Porsche calipers, so finding pads should be no problem if you just look for 993 turbo pads.

The composition of the remainder of the kit can vary a lot. Talk to these folks. They can sort out what you need and provide the parts.

There was no 2000 "C4" Audis so I have to presume that you are talking C4 Carrera Porsche. (??). In any event, here are the PNs for a recipe for Big Block Brembo/Porsche brakes for a C4 Audi UrS4 or UrS6:

Credit to Trent Wakelin for these part numbers:

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

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

Porsche 928 GTS front calipers ("Big Blacks"):
Porsche P/N -928-351-423-03 L, 928-351-424-03 R


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4D0 615 301 A or J (A was superceded by J)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

YMMV

I'm not sure how that is helpful. I assume from his measurement (12.25") that he is needing the 314X30 rotors available here. I thought maybe talking to Apikol might help him see all the options.

Since Mike does not provide any details about the vehicle or the parts he is searching for, there are many other possibilities that might be eliminated by talking to a knowledgable person rather than conducting a guessing game on the forum.

The car is a 1995.5 s6 with Porsche red calipers the pads that work in the caliper are from a 2000 Porsche. My rotors are not the 4do rotors as they are to big in diameter. The 312mm rotors ar th right diameter by the wrong depth? What are some other rotors with the right diameter? Do Porsche rotors fit our cars or are the bbk kits using a8 rotors? Thanks again mike

The problem is you are not identifying the type of bracket that was used to mount the caliper to the wheel bearing housing. Those that use RS2 brackets to mount the Big Reds/Blacks run the 323 x 30 rotors. However, the Euro UrS4s that didn't get the UFO brakes (don't ask), got an HP2 caliper and ran 314 x 30 rotors which might be what you are running. I think ECS made brackets that worked for that combo (photo of your brackets would help). See item 5 in this diagram:

Found them 441 euro rotors.... Thanks guys

UrS4boy

You found them where? (Others might want to know too);>)

For future reference: "The A8 323X30 rotor has all the same dimensions as the 314, but is available in the states. It fits the same as the 314s.... The rotors have the same offset dimension. The only difference in the rotors is the diameter."
