I guess the calipers are not too expensive to find used but that is one expensive rotor even compared to common competition brake kits.
Leading evidence: 'Use but' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Test stand' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Wouldn't call this "budget" by any stretch but it's a great use of OEM+ parts.

Suggestion
The hat hieght on the cayman is different then 996 so the pistons r not centered in the caliper if using stock parts?
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.

Hi everyone,
I have been working on piecing together a budget friendly brake setup. Initially I wanted to go with the 350mm rotors from a 997, but the caliper bolt spacing difference was not big enough between the C2 and C4s/Turbo calipers. So I spent a good amount of time searching for alternatives ranging from eccentric caliper studs, to spacers, to spindle swaps. All were very viable options.
But what I ended up with is an OEM Brembo 6-piston caliper and 380mm rotor from a GT4 Cayman. I got the brackets for the calipers machined to my specifications out of 6061 aluminum and currently fiddling with brake lines from a MK4 Golf. Everything seems to be fitting ok and I have not put it on my car yet, but I am so excited and wanted to share my progress so far.
I understand some of you will think it's pointless and it is ok to have your opinion.
I've attached a photo of my test stand. Excuse the mess in the background.
The 380 been done and is pretty cheap compared to a traditional BBK but there is no getting around rotor cost (unless you’re like me and get them from FCP).
What rotor hat r u using and how do make it work? The hat hieght on the cayman is different then 996 so the pistons r not centered in the caliper if using stock parts? Or did u machine the offset into the mointing bracket? What r u gonna do with the back to balance the brakes and lastly i hope u r planning on a 997gt3 master cyl upgrade to stiffen the pedal.
I machined the adapter bracket offset to match the OEM GT4 offset.
I am going to go with a 350mm rotor but stock caliper in the rear. I prefer more front biased brakes so that might work out fine for me.
And yes, I will be switching the master. However I will look into other options in addition to the GT3 master.
I guess the calipers are not too expensive to find used but that is one expensive rotor even compared to common competition brake kits. Wouldn't call this "budget" by any stretch but it's a great use of OEM+ parts.
Fair point! I would consider this a budget 380mm brake setup, but definitely not a budget brake setup.
The calipers are about $600 brand new, rotors are $900 from rennline, and pads and lines. All in all the setup will tally up to about $2000.
