Stage 2

• Base Engine: 4.2 V8 -340 BHP
• Performance upgrade by ECU reprogramming (engine control unit remapping)
• Performance air filter
• Exhaust system from catalyst back

Stage 2 consists of optimisation of engine management software, performance air filter and Milltek Sport exhaust system. The Milltek exhaust is available in a number of options.

Brake fluid upgrade

Brake fluid upgrade using Motul RBF600 fluid. A real must for serious drivers.

Motul RBF600 Factory Line brake fluid is a 100% synthetic brake fluid particularly suitable for the demands of racing and for those requiring a high performance brake fluid. This high performance DOT 4 brake fluid is particularly suitable for race applications and exceeds the DOT 5.1 and DOT 3 standards, except for viscosity at - 40°C (-40°F).

RBF 600 has extreme thermal resistance and stability. The very high boiling point (312°C / 593°F) of this brake fluid is better than conventional DOT 5.1 brake fluids and enables effective braking even under extreme conditions.

With its very high wet boiling point (216°C / 420°F), RBF 600 is also great in the rain. RBF600 is superior to conventional DOT 5.1 brake fluid (180°C / 356°F min) and DOT 4 (155°C / 311°F min) brake fluid.

RBF 600 brake fluid is suitable for all types of hydraulic actuated-brake and clutch systems requiring a non-silicone synthetic fluid. RBF600 is specially designed to resist the high temperature of racing brake (steel or carbon) and clutch systems.

RBF 600 Factoryline brake fluid meets standards:

• FMVSS 116
• DOT 4
• SAE J 1703

100% synthetic brake fluid from polyglycol bases.
