GRD WRX Stage 1 - 294BHP / 305ftlb Torque Running Millers Octane Boost (+2Ron) & Shell V-Power Fuel

This car has the following Packages installed.

GRD WRX Stage 1 Tuning Package With Optional Extras

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%.

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

GRD Drag 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.

With a unique Screamer Pipe design this exhaust system vents exhaust gases seperately from the exhaust turbine and turbo waste gate through a main 3" pipe and a second 1.5" pipe. Other exhausts on the market use an open neck design causing the paths of the exhaust gases collide once the turbos wastgate is opened, causing exhaust gas turbulance and reducing the speed at which gas can flow creating backpressure. This in turn slows down the turbo reducing the speed at which and its ability to flow air and causes exhaust gas to stay in the combustion chamber longer creating unwanted heat buildup, lowering the point of ignition advance before detonation will occur. This exhaust will give the advantage over a regular open neck downpipe of the ability to increase ignition advance, increase the speed at which the turbo can spool up and the amount of air which it can flow. All leading to a significant increase in both power and torque.

De-Cat Up Pipe - Unlike the WRX, this Up Pipe has no restrictive Cat increasing flow and compliments our 2.5" Stainless De-Cat System.

GRD Cold Air Intake - By eliminating the standard airbox resonator and snorkel we are able to source cold air directly from custom vents in the front foglight cover. This helps to dramatically increase airflow to the standard airbox, lowering inlet temperates and in turn give a significant increase in both power and torque.

This package does require STI foglight covers, however we can offer these as an option on most WRX models.

GRD Stage 2 Handling Package With Optional Extras

Whiteline Control Springs - Whiteline Control Springs are between 15-50% heavier in rate than standard to deliver a reduce squat, reduced body roll on turn and a reduction in braking nose dive will provide a pleasing, flatter squarer look on the road. Lowering height of around 25mm. Complete set, Front and Rear Springs

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 24mm - This is the 24mm 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.

Optional Extras

Whiteline 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 WRX Stage 2 Brake Package

STI Brembo Front Calipers - As fitted on Impreza STI. Due to the increased caliper size 17" STI wheels or 18" wheels are required for clearance.

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.

Goodridge Hoses - These race-bred brake lines are constructed from the finest quality hose, consisting of PTFE inner and stainless steel overbraid. They eliminate sponginess under heavy braking and increase braking efficiency while being abrasion and corrosion resistant.

AP 600F Brake Fluid - AP 600 Fluid has been developed for racing applications where higher than normal temperatures are being experienced and the ultimate in brake fluid performance is required.

GRD STI Rim & A048R Package

Yokohama A048R Semi Slick - The Advan A048R provides a new level of racetrack performance - combining the latest advances in road legal racing tyre design, construction and compounding. It's cutting edge design gibes you more precise control in high speed lateral transitions, a beeter footprint under braking and a predictable level of grip at high slip angles.

STI Gold Rims - These STI Rims are slightly wider than stock WRX Rims for clearance of the STI Brembo Front Caliper. A 225/45/17 Tyre is also required to fit this Rim.

GRD Full Vinyl Sticker Set

Full GRD Vinyl Car Set - Includes 3 large Greenwood Racing Developments logo's, 2 large GRD logo's and 2 web site address (www.greenwoodracing.co.uk) logo's.
