Sneek Peak: A Look Inside Magnus Racing’s ALMS Porsche GT3

  • Mike Kojima

,

Sneek Peak: A Look Inside Magnus Racings ALMS Porsche GT3
 The rear wing is a single element part and is pretty big.

The adjusters on the remote reservoir JRZ shocks are placed for easy access.  Sorry for the lack of good suspension pictures.  The team said the underneath of the car was secret and they would not let us photograph it.

 The stock Sachs Motorsports dampers were replaced with JRZ 4-way adjustable units.  The low and high speed compression damping is adjustable via knobs on the cannister.

In the rear, JRZ four way coilover dampers are used with the multilink rear suspension modified for adjustability with camber and toe adjustment. Like the front, the rear hubs are center locks and a similar blade adjustable tubular antisway bar is used.

 Low and high speed adjustments in rebound are done at the top of the shock shafts.

The brake system uses a dual master cylinder system with one circuit for the front and another for the rear.  A balance bar controls pedal force in-between the two master cylinders to adjust brake bias. A hydraulic adjustable proportioning valve is also used. The front calipers are big six piston Brembo monoblocks with a huge 380mm vented floating rotors on alloy hats.  Performance Friction racing brake pads are used. The rear brakes use a big 355mm vented floating rotor on an alloy hat with a 4 piston Brembo monoblock caliper.

 Big Brembo brakes do the job for stopping.  Large floating rotors are used as well.

 Dual master cylinders with pressure sensors for data logging.

 This knob adjusts the location of the brake pedal fulcrum in the balance bar.  This adjusts brake bias.

BBS forged alloy wheels center lock are used, 18×9.5″ with a 37mm offset with a 24/64-18 Advan slick for the front and an 18×12 with a 30mm offset and a 27/68-18 slick for the rear.

 Sneek Peak: A Look Inside Magnus Racings ALMS Porsche GT3
 Forged lightweight BBS wheel are adapted for centerlock use.  Advan slicks are used.
