Since purchasing a BMW G87 M2 in 2025, Suspension Secrets has been hard at work overhauling the chassis with upgrade parts to transform handling performance.
The Suspension Secrets G87 M2 has been on quite the adventure since it joined our development fleet last April. In a little over a year, we have progressed our M2 from bone stock to Fast Road and then Clubsport spec using our suspension upgrades.
During the last 12 months, the way the our G87 manages braking, cornering, steering inputs and power application has been transformed beyond recognition. And we’ve got the data to prove it thanks to our partnership with VBOX Motorsport, whose cutting-edge equipment allows us to collect tyre temperature information in real time, as well as lap times and G-force information.
On this front, we have another hugely exciting development in the pipeline that will revolutionise how we measure the performance of our upgrades. Full details will be revealed in the coming weeks so make sure you’re following our Instagram and Facebook accounts, and subscribed to our YouTube channel.
G87 M2 Suspension Upgrades
Arriving on the scene in late 2022, the rear-wheel-drive G87 M2 became the best-selling full M car in 2024 and 2025, with fans the world over appreciating its sheer power, sophisticated suspension and high level of tunability.
However, as we have found with our own development car, the G87 chassis is far from perfect.
Steering feel is muted, response to inputs not as sharp as it should be on an M car, and rear traction limited – especially on damp surfaces. These characteristics are more pronounced on circuit: During our car’s first track test in standard form, the amount of understeer we encountered at high cornering speeds was surprising to say the least. We also found the rear axle overwhelmed by the S58 engine’s twin-turbocharged delivery of 460hp.
Combined, these issues are immensely frustrating and mean you are playing a waiting game with the throttle both mid corner and on corner exit; too much throttle application early on will push the nose wide of the apex, and when it is possible to apply the gas towards corner exit, you’re then forced to fight oversteer.
It’s during these moments that you become distinctly aware of the M2’s 1,700kg+ kerb weight. Indeed, body control is another area to address on any G87 build because pitching and rolling is noticeable on the road and particularly apparent on track.
The Road to Clubsport
The grand plan with our G87 M2 is to turn it into a no-compromise track car. But right now, we’re optimising the package for Clubsport driving. In other words, ensuring the car is fully usable on the road but very fast on circuit with a few compromises in terms of practicalities; our G87 is now a two-seater thanks to the half-cage that replaced the rear seats.
And speaking of seats, we made the decision to go a different way than everyone else by replacing our M2’s original front seats with genuine M Carbon buckets retrimmed by Seamline in Cognac Vernasca leather to match the rest of the interior. This wasn’t an option from the factory and is a great talking point for our project. The finishing touches are Suspension Secrets logos in the headrests.
Handling Ambitions
From a technical viewpoint, having access to our own G87 M2 makes perfect sense. Since the model’s launch, we’ve built a comprehensive range of suspension upgrades which allow owners to reduce understeer, increase grip levels, improve traction and discover another level of driving enjoyment in their G87.
As with our hugely successful Porsche 718 Cayman GT4 build, we have taken a methodical step-by-step approach to upgrading the G87 M2 suspension. This allows us to demonstrate how each new part performs in isolation, and how it fits into a greater package.
The first upgrade we installed was the M2 CS+ Handling Pack (Fast Road), comprising our M2 front camber plates and M2 rear toe arms. The camber plates address the lack of camber adjustment on the M2’s front axle and allow more performance-oriented settings to be applied. This means more of the tyre contact patch can be utilised during hard cornering, improving grip and also tyre wear.
The upgraded adjustable rear toe arms feature solid rose joints in place of the factory rubber bushes to stop flexing, geometry changes and, ultimately, inconsistent handling when you’re pressing on.
M2 Lowering Springs and More
Next on our M2, we installed Eibach lowering springs to achieve a 25mm front ride height drop and 20mm reduction in rear ride height. As well as improving the G87’s road stance, this M2 upgrade lowers the car’s centre of gravity, meaning less hesitation as you turn into a corner, less pitching under braking and acceleration, and an overall improvement in handling performance.
The G87 lowering springs were combined with our adjustable front and rear drop links to ensure the anti-roll bars function as intended and don’t upset handling.
To advance our G87 M2 build towards Clubsport specification, we then installed our offset front caster bushes, which removed yet more soft rubber bushes from the chassis – this time in the front lower control arms. These M2 upgrades have the added benefit of introducing positive caster angle to the setup, which brings welcome weight to the steering and enhances turn-in response through dynamic camber gain.
Completing our G87 M2 Handling Pack 2 (Clubsport) was our rear traction arms, which were teamed with 305/30ZR19 tyre sizes all round to dramatically improve how this BMW transfers its power to the road and race track. During the M2’s recent track test at Anglesey Circuit, pro driver Chris Dymond also noted how the rear traction arms created more a neutral chassis balance in the early stages of a turn. This allowed him to be more committed going into high-speed corners and have confidence that the car would follow his steering input with accuracy.
State of Play
There is no mistaking the significant handling improvements we’ve made to the G87 platform. What was once an imprecise, uninspiring and unstable BMW M car is now so much more rewarding to drive on both the road and track.
For many owners, we think Clubsport spec is a great level to aim for in their M2 because you have the best of all worlds: sufficient comfort for driving on the road and yet the sharpness to trouble well-driven Porsches on track.
Of course, we could stop right here and be happy with a fast and fluent M2. But that’s not the Suspension Secrets way of doing things. We love finding ever more handling performance from a chassis by developing brand new upgrade parts, and that’s absolutely the approach we’ll be taking with the G87.
Make sure you don’t miss new developments in the coming weeks.
