I know a lot of you with steel brakes on these gen2 cars have complained about the response, feel and inconsistency of the brakes before so here's an example (expensive though it is) that we tackled. For PCCB cars I'd do the master cylinder upgrade for sure- as Steve found out it really helps. The steel ones feel considerably worse and even the master cylinder by itself didn't help all the way....

This local 2011 Cayman R was feeling a bit blue after a few track events when it came to its stock steel brakes. The pedal feel is notoriously mushy/inconsistent and many Gen2 Cayman owners have complained about this in comparison to their 911s. With R-compound tires and a quick driver at the track this otherwise nifty Cayman R needed a brake overhaul with a 14 inch 6-piston Brembo Brake Kit.

In for surgery:


The first port of call is the upgraded brake master cylinder, from a Gen2 GT3 with PCCB's:


The fronts are the very same brakes as on the 2006 Cayman S when it was first introduced. With the additional power and improved suspension Porsche really could have upped the ante for the Cayman R model...


The stock rear rotors were very worn and ready to be changed:


The Brembo goodies awaiting their turn:


The much larger and now 6-piston Brembo caliper vs smaller stock 4-piston:


Two piece slotted rotor with way more surface are vs the stock drilled and tired one...


Thicker and yet lighter too!:

Even the new 4-piston rear caliper is considerably larger:

Fronts installed:



Rears being installed:



The stock 19 inch Cayman R wheels are some of the nicest factory wheels Porsche has ever had so no changes there. Fitment is a-ok with the larger brakes:



Ready to go hit some local NorCal tracks... only this time armed with a more consistent brake pedal, improved cooling (to help deal with traction control brake wear interference) and way more bite!




A few track days later the owner reported back having been able to enjoy fade-free days. No noticeable fade and a consistent pedal that was no longer mushy/soft

That looks awesome. Nice work.

We see the big problem on the interseries cars is air and cooling to the brakes. Proabably same issue on a stock cayman or worse. Have you tried running the plastic air diverters that mount to the front A arms. Sorry dont know what they are technically called.

We used the same ones that come on the .2 RS and it really helped get some cooling to the front brakes. They still run hot until you run ducting.

Just curious, could you run 18 wheels with that brembo set up?

Take care

Cheers!
that's irritating eh! We talked about it before yes... In fact steve wanted to maybe get rid of his DRL's (street cars have blind) and try maybe funnel some air that way..... We did use RS cooling ducts at least when you have GT3 control arms (or RSS) but they have to be cut/machined down a lot vs on a GT3

And yes 18s would fit a-ok with the right offset.
