Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Does any one have the spec of the caliper and discs for all the models of 996? Both front and rear. I am looking for the 996 / 986 s fronts which I know will fit, but I can’t seem to find much on the 996 rears. I have the complete rear suspension set up, just google isn’t helping me with what size the rear brakes calipers are. I have a complete 2.7 986 as a parts car, I know the calipers are different, so I need to purchase the set. Any help would be appreciated. Thanks

POST 2Original post

i not completely clear on what you want to exactly know, as the specs for all models of the 996 doesn't answer the question Which car is this for?

Looking to get the complete spec list for all the different models of the 996 brake calipers. I have a 996 c4 shell, but I am slowly collecting all the parts I need to rebuild, I have the front suspension of a 986 2.7 that I’m using to get it rolling, I know I need the 996 / 986s front calipers, but any info on what rear caliper specs are, I cannot seem to find. For example, Could I use the 986 2.7 front calipers as rears on the 996? What are the differences etc. I know the C4S / turbo calipers need a different hub or adapter to make work with the front suspension, but what are the differences between the c4s calipers and the c4 standard ones? Thanks in advance

POST 4Original post

I usually go on autodoc, put the model in and see what comes up in the specs of the results.

It was more to see what the differences are between all the models too. Thought some one may have asked this before

it's been asked on a specific car basis You need 996 3.4 brakes on a 996, which are also the same spec as a 986 3.2 986 2.7 brakes are not for any 996

Exactly, that's what I said - put the model in and see what brakes it has.

Well first search for calipers came up with a rear caliper that supposedly fits most models from 1963 to 2005. It’s only a comparable remanufactured caliper from ERA. And only 2 piston vs 4 on eBay’s finding for rear 996 calipers.

Is that for both the front and the rears? I’d be interested to know the difference between the front 986 2.7 and rear 996/986s, they look similar but there must be some differences

POST 10Original post

986 2.7 brakes do not work on a 996, they are too small, the end

POST 11Original post

the front section between the 986 and 996 are very similar as that is how they were designed after the a-pillar it's all different

POST 12 / ORIGINAL POSTEROriginal post
