Project 2010 Porsche Cayman S


Built to run NASA’s German Touring Series (GTS) and PCA Club Racing

The Cayman was purchased brand new from Porsche with intentions of becoming a race car. After a few short trips on the street and debating by the owner whether he really wanted to tear apart such a beautiful and brand new car, it arrived at the shop and was ready for its conversion.

Interior;
The first thing to be done was to remove the interior and prepare the car for the roll cage to be installed which was done by BodyMotion Racing in New Jersey who is well experienced with Cayman roll cages.

For safety equipment, the Recaro SPG Pro Racer Hans seat was selected for its superior comfort and safety. To accompany the seat is the Schroth "Hans Style" Enduro harnesses. With their ease of adjustment they make a great choice for any race car.

Installed for racing purposes were the Schroth left and right side window nets and the SPA fire fighter system which was installed in Bonnet to avoid cluttering up the cockpit of the car.

Also Installed was the quick release for the momo steering wheel with built in steering angle sensor to allow for the traction control to remain working if needed. To dress things up the custom carbon fiber panels were added for switches, etc....

 
Suspension and Handling;
The shocks that were selected were the JRZ RS Pro's. The shocks are "double" adjustables with remote reservoirs and come as a complete kit from JRZ with eibach springs, solid front camber plates and solid rear upper shock mounts. To further improve the handling matched sway bars from TPC Racing were added along with adjustable bump steer correction rear toe links.

To keep everything stuck to the track are Hoosier R6's along with Forgeline 18" wheels.

 
Performance Engine and Driveline;

Engine performance enhancements were kept to a minimum as PCA class rules don't allow for much modification. The headers were replaced elimating the catalytic converters and new high flow mufflers were installed. Also the ECU was re-tuned to match the exhaust system to ultimately give a 30 HP gain. In addition to the power enhancements, the differential was swapped out for the tighter locking LSD from Guard Transmission.

 
Cooling Systems / Etc.;
From what we had heard before the start of the build, and what we have learned from testing, almost every fluid on the car has a heat issue once on track and pushed hard. To help reduce water temperatures, a factory Porsche 3rd. Center Radiator was added. Adding ducting to the brakes was no easy task, especially in the front, but after some some advice from other Porsche specialists and fabrication, a very effective way of ducting the brakes was developed. Continuing with the heating issues, two inline oil coolers were added for the transmission fluid. Engine oil temp has not been problem yet.
