Big thanks to 911 & Porsche World magazine for this article on our Cayman CS.
We have started with the Cayman CS project. Over the next few weeks we will be fitting the upgrades to our Cayman to make it the ultimate fast-road Cayman - something we like to call Cayman CS.
We quickly threw one of our 917 style wooden gear knobs on and started on the performance upgrades.
A simple brake pad and fluid swap turned into a nightmare when the last bleed nipple sheared off. This required drilling out and tapping for a new bleed nipple. We fitted Ferodo DS2500 pads and flushed the system with AP Formula DOT 5.1 fluid.
Next was to address the power steering system. 987.1 Caymans do not have a power steering fluid cooler. When running prolonged high RPM, the power steering fluid is being pumped around the system more than normal which increases it's temperature. With the inadequate cooling this could cause a failure of the rubber power steering hoses. The simple fix is to fit a power steering fluid cooler in the low pressure circuit.
Oil starvation is an issue on the M96 and M97 engines during hard cornering, especially with track tyres. We decided to fit a copy of the Porsche Motorsport X51 sump, it is slightly deeper which increases the engine oil capacity 0.6 litres.
In the next update we will be fitted a third radiator and the suspension upgrade.
