Derived from extensive track testing in the hands of professional drivers and utilising the best data analysis equipment, Suspension Secrets Circuit Handling Pack offers the perfect blend of components to transform the chassis of the 718 Cayman GT4 RS out on track. 

After multiple track tests with GT4 RS' as standard with the stock components maximised in terms of their setup we began developing a list of improvements for the handling and designed the solutions to each item identified. All of Suspension Secrets designed solutions are included in this handling pack to maximise grip, utilise the full contact patch of the tyre and improve the chassis balance substantially. 

The main benefits of the Suspension Secrets Circuit Handling Pack for the Porsche 718 Cayman GT4 RS are:

• Greatly improved cornering grip
• Reduced understeer
• Lower ride height at the front and rear
• Removal of bump-steer resulting in more accurate steering at the limit
• Reduced body roll and increased control due to stiffer springs front and rear
• Increased braking stability
• More neutral chassis balance
• Improved tyre wear due to increased front and rear camber

The pack itself contains multiple upgraded components that work as direct replacements for existing OEM parts; no additional chassis or body modifications are required. The Circuit Handling Pack includes:

• Suspension Secrets top mounts with increased camber and caster

• Upgraded front and rear Eibach racing springs with increased (stiffer) spring rate and shorter than OEM to allow for increased lowering of the chassis

• Suspension Secrets spring cups which help retain the original bump/droop ratio of the damper even after the car has been lowered

• Suspension Secrets bump-steer tie rod ends which help to remove unwanted bump-steer

• Suspension Secrets adjustable rear toe arms to allow for unrestricted rear camber settings

• Suspension Secrets camber shim kit 

PLEASE NOTE: The Track Focused option includes stiffer front and rear springs
