Suspension Secrets Handling Pack 1 (Fast Road) – BMW F20 M135i / M140i
Transform the handling of your BMW F20 M135i or M140i with Suspension Secrets Handling Pack 1, a carefully selected fast-road suspension package designed to improve cornering performance while retaining everyday road usability.
The standard F20 M135i/M140i can suffer from excessive body roll, instability under heavy braking and limited factory geometry adjustment. Handling Pack 1 addresses these weaknesses by combining complementary suspension upgrades into one complete package.
The result is a more responsive, better-controlled and more confidence-inspiring chassis without pushing the car towards an excessively harsh or uncompromising setup.
Why Choose Handling Pack 1?
Handling Pack 1 is designed as the first stage in Suspension Secrets' BMW F20 handling upgrade range.
It focuses on the modifications that deliver meaningful improvements for road and fast-road use while preserving refinement.
Potential benefits include:
- Reduced body roll
- Improved turn-in
- Better cornering stability
- Increased geometry adjustment
- Improved braking stability
- More predictable chassis behaviour
- Better front and rear axle control
- Road-friendly suspension setup
What's Included?
Handling Pack 1 includes:
- Suspension Secrets Camber/Caster Plates
- Suspension Secrets Adjustable Front Drop Links
- Suspension Secrets Adjustable Rear Drop Links
- Suspension Secrets Adjustable Rear Toe Arms
Together, these components address ride height, chassis control and geometry adjustment rather than focusing on a single area of the suspension.
Suspension Secrets Camber/Caster Plates
The factory F20 suspension provides relatively limited front geometry adjustment.
Suspension Secrets Camber/Caster Plates introduce additional adjustment, allowing the front-end geometry to be tailored more precisely.
This can help improve:
- Turn-in response
- Front-end grip
- Cornering balance
- Steering accuracy
- Tyre contact during harder driving
Adjustable Front & Rear Drop Links
Lowering a car changes the operating position of the anti-roll bars.
Adjustable drop links allow the anti-roll bar system to be set correctly at the new ride height.
Potential benefits include:
- Reduced unwanted anti-roll bar preload
- More consistent suspension behaviour
- Improved left-to-right chassis balance
- Better anti-roll bar operation
Both front and rear adjustable drop links are included.
Adjustable Rear Toe Arms
The adjustable rear toe arms provide additional control over rear wheel alignment.
This becomes especially useful after lowering the car or when setting up a more performance-focused geometry.
Correct rear toe can influence:
- High-speed stability
- Corner-entry behaviour
- Traction
- Rear-end confidence
- Tyre wear
Reduced Body Roll
The suspension components within the package work together to improve overall body control.
Reducing excessive movement through corners can make the car feel:
- More composed
- More responsive
- More predictable
- Easier to place accurately on the road
Improved Braking Stability
The standard F20 chassis can feel unsettled under heavy braking.
By improving suspension control and geometry, Handling Pack 1 helps create a more stable platform when braking hard.
This can give the driver greater confidence during fast-road driving.
Improved Geometry Adjustment
One of the major limitations of the standard F20 chassis is the relatively small amount of factory alignment adjustment.
Handling Pack 1 significantly expands your ability to optimise the car's geometry through:
- Front camber adjustment
- Front caster adjustment
- Rear toe adjustment
- Correct anti-roll bar positioning
This allows the suspension setup to be tailored more accurately to the intended use of the car.
Road-Friendly Performance
The focus of Handling Pack 1 is fast-road performance rather than outright track stiffness.
Suspension Secrets states that the individual upgrades are chosen to improve handling without introducing a noticeable increase in noise, vibration or harshness during normal road use.
This makes the package particularly well suited to cars that still need to remain comfortable and usable day to day.
Ideal for Fast-Road Builds
Handling Pack 1 is particularly suited to:
- Daily-driven M135i and M140i models
- Fast-road cars
- Weekend performance builds
- Cars running performance tyres
- Drivers wanting better geometry control
- Owners who want improved handling without creating a dedicated track car
Works Well With Other Upgrades
The package can form the foundation of a wider chassis build alongside:
- Performance tyres
- Uprated brakes
- Limited slip differential
- Chassis bushes
- Anti-roll bars
- Additional geometry components
Starting with a balanced suspension and alignment setup allows other handling upgrades to work more effectively.
Professional Installation Recommended
Because the package includes multiple suspension and geometry components, professional installation is strongly recommended.
After installation, the car should receive:
- Ride-height setup
- Full suspension inspection
- Anti-roll bar setup
- Wheel alignment
- Performance geometry setup
Geometry Setup
A professional geometry setup is an important part of getting the most from Handling Pack 1.
Camber, caster and toe settings should be selected around:
- Road use
- Tyre choice
- Ride height
- Driving style
- Intended level of performance
