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

  • Mike Kojima

,

 Sneek Peak: A Look Inside Magnus Racings ALMS Porsche GT3
 The doors, fenders, hood and deck lid are all factory lightweight carbon fibers parts.  Look how well finished the doors are.  The fit and finish of the car really impressed us and it’s a race car!

This hood mounted vent is the air intake for the cabin ventilation system.  Note the roll cage tube going forward through the firewall to the front strut tower.

The factory doors, rear lid, hood, front and rear fenders are all replaced with lightweight carbon fiber parts.  All glass is replaced with light and strong polycarbonate parts. An adjustable carbon fiber rear wing is added as is a wind tunnel test front splitter.  The front airflow for the engine heat exchangers is modified so the air exits through the front hood.  This helps improve aerodynamics.

 Sneek Peak: A Look Inside Magnus Racings ALMS Porsche GT3
 The cage has super clean welds, nice triangulation and gusseting.  We would guess that since these are mass produced, the parts are welded on jigs and the bends are all standardized.

HANS compatible OMP seat and HANS compatible six point harnesses.

The stock gas tank is removed and replaced with a 100 liter fuel cell.  An air jack system is added and an electronically activated fire system is installed. A HANS compatible OMP racing seat with head protection covered with fire retardant upholstery and matched with HANS optimized six point racing harnesses is also fitted. The factory steering wheel is replaced with an OMP racing part with a quick release hub on a steering column adjustable for length and height. A Motec ADL2 electronic data logging display is fitted into the dash.

 The front trunk holds a 100 liter fuel cell,  dual Bosch Motorsports 044 fuel pumps with a fuel surge tank, an air jack and dual master cylinders.  You can also see the remote reservoirs for the JRZ 4-way adjustable front shocks.

The suspension of the car is pretty trick but straightforward.  The front McPherson struts are fortified with JRZ four way adjustable coilovers replacing the factory Sachs motorsports units.  The control arms are fitted with spherical bearings and modified for camber and caster adjustability.  The hubs are modified for the use of center lock wheel retention.  A race type tubular antisway bar is used with rotating blade end links.  The blade links allow easy adjustability and can be rotated through seven discrete adjustment positions.

The front splitter gives a significant amount of downforce.

 A carbon adjustable rear wing is standard equipment from the factory.

The wing bolts directly to the chassis.  You can see the adjusting mechanism here.
