Suspension Secrets Circuit Handling Pack Kinematics Kit Stage 2 For Porsche 718 GT4RS

Take your GT4 RS to the next level out on track with our Stage 2 Kinematics Kit. Adding to our already popular stage 1 Kinematics Kit, this kit offers additional upgrades for the rear axle with the option of rear top mounts. 

Derived from extensive track testing in the hands of professional drivers and utilising the best data analysis equipment, our Stage 2 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 our 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. 

To take the track performance of the GT4 RS one step further we developed a solution to allow the rear tyre widths to also be increased beyond the stock sizes. We have made this possible with our options of Stage 1 Rear Top Mounts and Stage 2 Rear Top Mounts. Our Stage 1 Rear Top Mounts will allow a 305 width rear tyre to be used on a standard rear wheel and clear all body work and suspension components too. Our Stage 2 Rear Top Mounts will allow for tyre widths of up to 325 profile but will require an aftermarket wheel to achieve this. Please see the listing for the Stage 2 Rear Top Mounts for wheel specifications and options. 

The main benefits of the Suspension Secrets Circuit Handling Pack Stage 2 for the Porsche 718 Cayman GT4 RS are:

• Greatly improved cornering grip
• Reduced understeer
• Options to increase rear tyre widths
• 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 front/softer rear) spring rate and shorter than OEM to allow for increased lowering of the chassis
   
• Suspension Secrets rear top mounts that allow up to a 305 rear tyre width (stage 1) or a 325 rear tyre width (stage 2)

• 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

The technical highlights of our Porsche Circuit Handling Pack include:

• Increased positive caster

• Increased bump-to-droop ratio by 15mm with a lower front ride height, which increases damper efficiency

• Increased negative front axle camber with a minimum of 2.5 degrees and a maximum of 4.5 degrees

• Complete removal of bump-steer

• Rear camber shims increased rear axle negative camber by an additional 1 degree
