GRD STI Stage 1 Tuning Package With Optional Extras

GRD Sport Exhaust System - Weighing in at just 16KG`s this exhaust is possibly the lightest on the market - a massive 40% lighter than the standard system. Using fully slip jointed stainless steel construction this exhaust gives exceptionally good flow as it utilises a very straight and smooth exhaust path.

Fully Road Legal and MOT friendly this exhaust has all the same features as the GRD Race Exhaust System but uses a 300 CELL Sports Catalitic Convertor to help it to conform with current MOT exhaust emmisions requirements. This will however reduce exhaust gas flow, slightly reducing potential power output especially on high power applications.

Free Flow Air Box Panel Filter - High performance replacement for the original panel air filter. Constructed from a cotton weave which increases air flow by upto 40%.

Syntek Motorsport Fuel Pump - A crucial part to any engine modifications, is the ability to reliably supply your engine with enough fuel. This pump directly replaces the standard unit and has the ability to supply 2.25 litres per minute @ 5 bar pressure. The standard pump generates 1.1 litres per minute @ 5 bar.

EcuTek ECU - We use EcuTek software to reprogram your ECU via the diagnostic port of the car. We retain all the car's clever electronics but re-map ignition curves, fuel maps and the closed loop boost control system. The ECU remains programmable so if in the future something needs to be changed then we can. The only way to tell that that either conversion has been performed is to drive the car. There are no visual clues. Even the Subaru diagnostic tool does not show that the ECU has undergone brain surgery.

Rolling Road Tested - Our Dyno Dynamics chassis dynamometer measures engine power via the driving wheels in an accurate and repeatable method. Your vehicle's dyno runs are recorded in real time, and printed out in full color for your records.

Optional Extras

Exhaust Downpipe Heat Wrapped - This serves 2 purposes. To reduce heat soak into the engine bay and to keep the internal pipe wall temperatures up to aid the removal of waste gases through the exhaust system.

GRD STI Stage 1 Handling Package With Optional Extras

Whiteline Adjustable Front Anti-Roll Bar 22mm - This is the 22mm Front Adjustable Anti-Roll Bar from Whiteline for those wanting to play with the roll bar stiffness. Their objective is to reduce sway, or bodyroll, and stabilise a vehicle under lateral (cornering) forces.

Whiteline Adjustable Rear Anti-Roll Bar 22mm - This is the 22mm Rear Adjustable Anti-Roll Bar from Whiteline for those wanting to play with the roll bar stiffness. Their objective is to reduce sway, or bodyroll, and stabilise a vehicle under lateral (cornering) forces.

Whiteline Anti-Lift Kit - Whiteline Anti-Lift Kit (ALK) is designed to add 0.5 deg static positive castor to both front wheels while introducing a substantial amount of front anti-lift. The anodized alloy mounts coupled with the low compliance polyurethane bushings oppose front lift under acceleration while delivering up to +1 degree more positive caster. This leads to superior traction, reducing understeer allowing more power, faster acceleration and cornering. The additional static caster coupled with the new firmer bushings, deliver more dynamic caster dramatically sharpening initial turn-in response, forcing more consistent alignment angles through the corner allowing higher exit speeds.

Geometry Laser Tuned - We use Pro-Align Hunter 511 Computerised Wheel Alignment System.

Optional Extras

Whiteline Front & Rear Drop Links - These forged aluminium links reduce flexing and therefore effectively increase the rear roll bar stiffness; this helps reduce any natural tendency to understeer.

Whiteline Steering Rack Bushes - These replace the standard Steering Rack Bushes and offer a better steering wheel weight and more direct feel.

GRD STI Stage 1 Brake Package

EBC Red Stuff Ceramic Pads Front & Rear - This is a truly impressive fast road pad for repeated heavy braking. It emits far less dust than semi-metallic pads and has been proven to stop a saloon car 13 metres quicker than OEM pads from 100mph/160kph. Features EBC Brake-InTM surface coating which conditions rotor surface and accelerates pad bed-in.

EBC Turbo Groove Discs Front & Rear - The wider slot actually draws cool air across the pad surface keeping pads and rotors cooler. They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale and become ineffective in our opinion. The blind drilled holes break down surface gases when braking from speed but do not weaken the rotor cross section as can happen with through drilling, thereby lessening the chance of rotors cracking over time and heavy use.

GRD PFF7 Rim & Parada Package

Yokohama Parada Spec-2 - The Parada Spec-2 features the latest silica compounding technology, providing even greater performance through a more evenly reinforced tread. This improvement puts Parada Spec-2's acceleration, dry and wet grip, and braking ability in a league of its own without sacrificing durability.

Prodrive PFF7 18" Rims - Prodrive’s PFF-7 wheel is a seven spoke design which uses special flow forming construction techniques. These enable the wheel to be made lighter than standard die cast wheels without sacrificing any of the wheel’s strength or durability. The wheel is manufactured for Prodrive by Speedline in Italy and is available as an 18" rim in bright flitter or gold finish.
