Whilst lowering the ride height of your Boxster/Cayman is a great way of improving handling, it can also induce bump-steer.

Bump-steer occurs after a car has been lowered. The lower ride height changes the angles of the suspension arms and tie rods relative to one another. This change in angle affects the arc patterns of the suspension arms and the tie rods, reducing the range of movement available at the wheel hub. This causes the front toe geometry angle to change dynamically when driving. This constant change of toe angles results in instability and understeer when driving hard.

To eliminate bump-steer, we designed our Suspension Secrets Adjustable Bump Steer Tie Rod Ends for the Porsche Boxster/Cayman 987. Our stainless steel tie rod ends can be shimmed in order to eliminate bump-steer, allowing you to exploit the dynamic benefits of a lower ride height without any of the downsides.

The key features of the Suspension Secrets Adjustable Bump Steer Tie Rod Ends for the Porsche Boxster/Cayman 987 are:

  • Complete removal of bump-steer
  • Reduced understeer
  • Increased steering accuracy
  • Reduced understeer

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.

Geometry Explained

Bump Steer
Bump steer is highly undesirable within racing especially on tracks or surfaces that contain bumps. If the suspension is constantly transitioning between bump and droop, then a car with bump steer will constantly be shifting the steering angle of the car and will make the front end very unstable at high speeds. The bump steer in the system will affect the precisely designed Ackermann steering geometry and will make the steering more unpredictable for the driver.

Bump steer can provide an advantage to the rear end of a car on a smooth circuit effectively providing “active toe” during cornering. This can be used on a front wheel drive car to produce toe out, when the suspension is in bump, at the rear of the car to encourage oversteer on turn in; removing understeer characteristics.

Product Development

All Suspension Secrets upgrades are designed, developed and manufactured in-house. This process includes prototyping new products using CAD and 3D printing technology, and extensive rear-world testing with professional racing drivers. Sophisticated motorsport data capturing equipment allows us to measure the handling performance gains achieved by our parts.

Effortless & Accurate

The results have exceeded my expectations, I'm really pleased with the car. The ride is similar to stock but it's taken the jitteryness away over small ripples in the road. I was slightly apprehensive that the stock dampers might be exposed but I needn't have worried, the car rides exactly as I'd expect & want from a roadgoing M-car. The real revelation is the steering, I could feel the difference as soon as I turned out of your premises. Gone is the sluggish, heavy response - it's now quick, effortless & accurate, almost as if the power steering had been switched off beforehand. The car feels like it's 200kg lighter but at the same time, more solid & composed. For me, it's a perfectly-judged road setup - thanks again

Recently bought a 2025 M3 LCI which seemed ok out of the box. In the wet there was quite bad understeer and slightly unpredictable transition into oversteer. The CS+ handling package transformed the car. The grip is ridiculous, feel is improved, can really lean on the car. Driving in the wet traction is like it’s dry, extremely stable. Car is predictable, any transition to understeer or oversteer is communicated and feels like slow motion with plenty of time to correct. Feel like all the handling of a CS car with all the comfort or a regular M car. Absolutely love the car now.
