Hi all!

I wonder if the Porsche 993 Carrera brake calipers are unique to Porsche or have the same calipers been used om any other car make? Would be nice to locate a set on a scrapyard and use after a refresh while I have mine refurbished!

Most cars except 911s end up in scrapyards after 15-20 years...

They are made by BREMBO with Porsche Logo

To Porsche spec which entails more robust bolts & specific piston sizes,

AFAIK only some special Audi models ever used them

Thanks Bill makes total sense.

Thanks! Maybe the 1995 RS2, the one with the 993 blinkers?

Pretty well known car in VW/Audi circles. I always wanted one of these in my GTI days (1990's)

If I recall correctly, they had 964RS brakes which I believe were front calipers that were the same size as stock 993 brakes, except the mounting bosses were raised to space them out to accommodate one piece 322mm rotors (same size as big reds). Pretty sure the 964RS rear brakes are 1:1 the stock 993 rear brakes.

Bill can probably correct any fuzzy memory I have.

I used to own an RS2. It had brakes from Porsche. Cup wheels from the 964 and D90 as winters. If fitted with the big reds you could only use the Cup wheels. Some owners put big reds on the car from the 993 turbo/4S.

Porsche / Audi did tons of collaboration over the years ... now obviously Porsche is under the VAG umbrella and Subsidiary of Audi.

Porsche is a subsidiary to VAG and so are Audi.
Porsche and Audi are sister companies to eachother.

But that happened only recently ... However, they worked close together for decades. One source of the Porsche family's income was a royalty for every VW beetle build.

Porsche build for a while even cars for Mercedes!

Here's a good alternative to Big Reds:

Be very careful with these - we had a look at using these and they are far inferior despite being a direct copy.

Hi Chris
can you elaborate?
These calipers sold by design911 are from JP Dansk (https://www.jpgroupclassic.com/), a very reputable company from Denmark, which does a lot of OEM stuff for VW, Porsche and Volvo. i'm using these calipers on the track, no issues for now.

No. The brake caliper design belongs to their braking system supplier as Porshe neither engineers or designs brakes. Their supplier does. The supplier is given performance and fit specifications from where they adapt one of the proven designs in their catalog of designs and submits it to Porsche for performance testing. Porsche assembles cars and designs certain systems strongly associated with their brand such as engines. As far as fit goes caliper mounting and positioning are adapted to a specific car's deign at the wheel end. For this reason, I feel, it would be a stroke of luck if the mounting points on two different makes of vehicles happen to be the same. Generally, cars have proprietary wheel-end designs so sales of service parts are captured. It is interesting that in air-brake heavy truck the designs of the brake system components between suppliers are nearly identical and interchangeable between tier-one suppliers as the fleet vehicle market is interested in minimizing servicing costs and would reject proprietary designs.
