Increase cornering grip and stability with our Suspension Secrets Adjustable Rear Upper Third Link Arms for the BMW F20 M135i/M140i.

As standard, the BMW F20 M135i/M140i's rear upper third links are not adjustable. This can create an issue and increased tension on the third links when setting high levels of camber at the rear axle using an adjustable upper rear camber arm. 

To solve this, we designed our Suspension Secrets BMW F20 M135i/M140i Adjustable Rear Upper Third Link Arms, which allow for a greater range of camber adjustment and allow for the safe adjustment of camber at the rear axle for track use. 

The main benefits of our Suspension Secrets Adjustable Rear Upper Third Link Arms for the BMW F20 M135i/M140i are:

• Greatly increased cornering grip and stability

• Wider range of rear camber adjustment compared to stock, allowing more aggressive set ups to be applied

• Reduced binding of ball joints and bearings when track camber settings are installed

• Improved mid-corner and corner-exit traction

• Increased chassis balance from increased negative rear camber

• Necessary to make best use of semi-slick or slick tyres

Suspension Secrets' products are designed and manufactured in the UK. Our products are made from billet aircraft-grade 6082 T6 aluminium and corrosion-resistant 316 stainless steel. We use motorsport-spec Fluro bearings for maximum performance and longevity.
