The first step into achieving the ultimate handling for your BMW G80 M3 / G82 M4 on the roads is our Suspension Secrets CS+ Handling Package. Out of the factory the front and rear axles are still limited in their own ways. 

The front axle lacks any camber adjustment and doesn't have enough from the factory for spirited driving. This leads to understeer, a lack of feel and feedback through the steering wheel and premature outer edge tyre wear. The solution to this is to increase camber at the front axle and also increase caster too. A common upgrade on the BMW CS and CSL models is a fixed increase camber front hub to reduce the understeer and increase front end grip. 

With our camber plates fitted, not only can you get CS/CSL levels of camber at the front axle, you can go beyond that if you wanted to head out on track in the future. Our camber plates also increase the caster at the front axle unlike any of the CS/CSL upgrades. The additional caster improves steering feel and feedback for the driver which is significantly lacking as standard. 

At the rear of the car, the rubber bushed and constrained adjustment range rear toe arms also limit the levels of grip and stability from the car. To combat this, the M division uprated the rear toe arms on the G82 M4 CSL with solid rear arms. This solves the flex but not the adjustment range issues. 

With our Suspension Secrets Adjustable Rear Toe Arms fitted, the solid rose joints eliminate all the flex from the rear arm, keeping grip levels much more consistent and stable at speeds. The added adjustment range by way of our easy access adjuster also means that no compromises need to be made at the rear axle in terms of geometry allowing you to set the car with optimum camber and toe settings. 

With the camber plates and toe arms combined, you can achieve a setup beyond that of the CS and CSL BMW M car models, taking your on road performance and enjoyment to the next level.
