2004 996TT GT660 with Bilstein PSS10, & HRE C-21 Wheels

This classic-looking silver 996TT originally "only" came in for a mild Stage II upgrade but ended up staying a while longer for a full EVOMS GT660 power kit, Bilstein PSS10 Suspension and some light-weight HRE Competition wheels.

First things first, off comes the bumper, stock exhaust and the rest of the restrictive gear:


On go the GT28 based turbo chargers. Obviously bigger than the factory K16 turbos they still provide a very quick spool.



With increased boost pressure the factory hoses are not going to cut it so the EVOMS boost hoose upgrade has to be installed:


In goes the EVOMS V-Flow intake system and Hitachi MAF kit.


In order to support this sort of power level a Sachs/GT2 SharkWerks Stage II Clutch system has to be installed.


The EVO B&M shifter was also installed for a reduction in throw and more precise feel (essential due to the sloppy feel of the factory mechanism)


The Bilstein Coil Over kit has 10 levels of Dampening that are easily adjustable via the knob. The car was lowered only an inch.


The 11.5 inch wide 18 inch C-21 wheels (in brushed/clear finish) were wrapped with Michelin Pilot Sport 2 tires in 315 GT2 sizing for better traction.


There she is ready for "take off".
