My 986 Boxster S has front Brembo big disk kit, (i.e.: large floating rotors and 6 piston calipers).
In my quest to have firmer brake, I ordered a GT3 Master Cylinder.
..But, I found that this is not compatible with the plumbing of a 986, as the two "outlets" of OEM MC are : One with a m10 tube nut and the other with m12 tube nut.
The GT3 MC is different, as both outlets are with m12 tube nuts !!

THE big question : do you know where to get an adapter, that would be female m10 tube nut, and male m12 tube nut, ..to make one of the outlet of the GT3 MC compatible with the 986 tube ??

I'm in search for this part....

Thanks A LOT.
A very good thread, for all who do NOT like the natural "mushy" brake pedal feel of the 986s.

Install done, now, I can really confirm : This is a MAJOR-MAJOR IMPROVEMENT !
The brake feeling is 100% different, I felt that I had good brake, ..since I had the the Brembo big brake kit installed (on the front), with large rotors and 6 pistons caliper, but always felt that response was "a bit mushy" !
My brake are flushed 2 or 3 time per year, (using Motul racing 600 liquid), but still, I never had the feeling of a rock solid brake pedal.
Now, I have the TRW PMN166 Master cylinder, instead of the OEM master cylinder, ..and I can say that this is a COMPLETE other world !
I feel now that I have the perfect brake, a real amazing difference.
