Suspension Secrets Adjustable Rear Upper Third Link Arms – BMW 1M
Increase rear-end grip, stability and geometry flexibility on your BMW E82 1M with Suspension Secrets Adjustable Rear Upper Third Link Arms.
The standard rear upper third links are non-adjustable. When more aggressive rear camber settings are introduced using adjustable upper camber arms, this can increase tension and binding within the rear suspension.
Suspension Secrets developed these adjustable third links to reduce that problem and allow more aggressive rear geometry to be set up safely and accurately for road and track use.
Greater Rear Geometry Adjustment
The factory rear upper third links have a fixed length, which can become restrictive when increasing negative rear camber.
By adding adjustability, these Suspension Secrets third link arms allow the rear suspension geometry to be set more appropriately alongside adjustable camber arms.
This is particularly useful for:
- Track-focused geometry
- Higher levels of negative rear camber
- Semi-slick tyres
- Slick tyres
- Lowered cars
- Coilover-equipped cars
Reduced Binding at Aggressive Camber Settings
One of the main reasons for fitting adjustable third links is to reduce unwanted tension and binding when more aggressive rear camber settings are used.
Without sufficient adjustment, the factory fixed-length link can place additional load through the ball joints and bearings as the geometry is changed.
The adjustable design allows the arm length to be set correctly, helping the rear suspension move through its intended range with less unwanted preload or bind.
Increased Cornering Grip & Stability
When used as part of a correctly configured rear geometry setup, these arms can support increased negative camber and help improve:
- Mid-corner grip
- Rear-end stability
- Corner-exit traction
- Chassis balance
- Consistency under load
The benefit comes from being able to achieve more suitable rear suspension geometry rather than from the arm alone.
Better Support for Rear Camber Adjustment
These third link arms are particularly useful when paired with adjustable rear upper camber arms.
Together, they allow the rear axle to accommodate more aggressive camber settings while helping prevent the fixed third link from being forced into an unsuitable position.
This makes them especially relevant for more serious road and track builds.
Improved Use of Performance Tyres
Semi-slick and slick tyres can generate much greater cornering loads than conventional road tyres.
A wider range of rear geometry adjustment allows the tyre to maintain a more effective contact patch during hard cornering.
These arms can therefore form an important part of a setup designed around:
- High-grip road tyres
- Semi-slick tyres
- Slick tyres
- Track-focused suspension
- Motorsport geometry
Motorsport-Spec Fluro Bearings
Suspension Secrets uses motorsport-spec Fluro bearings within the arm assembly.
These are selected for:
- Reduced unwanted compliance
- Precise suspension movement
- High load capability
- Consistent geometry
- Long-term performance
As with other spherical-bearing suspension components, some increase in mechanical feedback may be noticeable compared with the standard rubber-mounted setup.
UK Designed & Manufactured
Suspension Secrets designs and manufactures these arms in the UK.
Construction includes:
- Billet 6082 T6 aircraft-grade aluminium
- Corrosion-resistant 316 stainless steel
- Motorsport-spec Fluro bearings
These materials are chosen for strength, durability and suitability for demanding road and track use.
Key Benefits
- Greater rear geometry adjustment
- Supports higher levels of negative rear camber
- Reduced binding of rear ball joints and bearings
- Reduced unwanted tension in the rear suspension
- Improved mid-corner grip
- Improved corner-exit traction
- Increased rear stability
- Improved chassis balance
- Better suitability for semi-slick and slick tyres
- Motorsport-spec Fluro bearings
- Billet 6082 T6 aluminium construction
- Corrosion-resistant 316 stainless-steel components
- Designed and manufactured in the UK
Best Used with Adjustable Rear Camber Arms
These third link arms are especially useful when the car is also fitted with adjustable rear upper camber arms.
The camber arms provide the increased adjustment range, while the third links allow the rest of the rear suspension geometry to accommodate those more aggressive settings without introducing excessive bind.
Vehicle Fitment
Designed for:
- BMW E82 1M Coupe
If you are unsure whether these arms are suitable for your current suspension and geometry setup, please contact The Rosso Corsa Collective before ordering.
Professional Installation & Geometry Setup Recommended
Professional installation is strongly recommended.
After fitting, the vehicle should receive a full four-wheel geometry setup so camber, toe and related rear suspension settings can be configured correctly around the intended road or track use.
