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.
Let customers speak for us
Excellent made product from quality material. Very happy 😃
Thanks guys excellent service. The Surface Transforms Carbon Ceramic brakes are mega, just done Anglesey and they performed brilliantly, great feel, awesome stopping power and ran much cooler than the standard steel brakes on my GT3. The set up also feels really nice the steering is calmer and more settled on bumpy old back roads(just been to Dumfries on the passes) and has improved the front end on Anglesey’s long late apex corners.
These toe arms are a game-changer for my GR Supra! Paired with KW V3s and solid bushings, they sharpened handling and eliminated rear-end instability on fast road (yet to test on track but will be soon). Adjustable rose joints make alignment precise, boosting corner exit stability with high torque (~700 Nm). Minimal NVH increase on the roads mean there is no real trade off with the upgrade. These are really well made. Comparing them to the stock ones after removal you can defiantly see where your money is going—essential for track enthusiasts!
A great upgrade for my G87 - the car now loves to turn, drives straight and feels so much more agile. The guys at suspension secrets are very knowledgable and super helpful - first class service.
Amazing service and amazing quality parts.
Suspension Secrets Adjustable Camber & Caster Plates - BMW F22 M235i / M240i
Item received as described, well packed and very fast shipping. I am very happy with the product.
These are beautifully machined product.
Fitting was easy, looking forward the the results on the track.
fantastic follow up and advice from the crew at Suspension Secrets on setup as well.
My part stuck at customs i dont have it
I received the package to find very high quality hardware including the hose which was very nice to see. I had my mechanic/body shop complete the install and it looks as if the air entrance ports were always there and part of BMW's design. Granted they should have corrected this airflow issue years ago, it certain looks the part. I live in Texas and it's the dead of summer here in July. I ran the car at my track this past weekend in 100 degree weather for 4-30 min sessions and the air flow worked perfectly as advertised. Not a single brake fade lap even with the hardest braking from 135 mph. Top Notch so far!!
The difference on the cornering is astonishing
Had the SS handling pack fitted to my car, track manners are now spot on with little to no loss to road compliance.
The sharpness of the front end is now on another level. A most for all 991.2 in my opinion.
Excellent quality! Excellent customer service! I've never seen more friendly and helpful folks. Thank You SS people!
Great quality and super helpful staff! Thanks for great products! Especially big big thanks to Mathhew who shipped me new Öhlins specific top nut so quickly! Thanks!
