If you're looking for a coilover setup for your BMW E36 that works on the street and at the track without beating you up on the drive home, the ISR Performance Pro Series coilovers are built for that dual-purpose role. They give you damping control and adjustable suspension tuning while keeping the ride comfortable enough to live with day to day, and the front pillowball mounts and high-end Japanese bearings put the build quality where it counts. These do not fit the E36 Compact.
What It Is
The ISR Pro Series coilovers are an adjustable suspension system for the BMW E36, designed for combined street and track use. The fronts are full coilover assemblies with pillowball upper mounts, while the rears use a separate spring and shock in the factory bucket location, which is the standard arrangement for the E36 rear suspension. The system features 32-way adjustable damping and ships with 6kg/mm front and 8kg/mm rear springs.
What It Does
These coilovers replace the factory suspension to give you control over both ride height and damping, so you can dial in the handling you want without committing to a single fixed setup. The 6kg/mm front and 8kg/mm rear spring rates are chosen to tighten up body control and improve handling while still riding comfortably enough for daily driving. Pair that with the adjustable damping and you can run a softer setting for the street and firm things up for a track day.
32-Way Adjustable Damping
The Pro Series gives you 32 clicks of damping adjustment, from soft to firm. Damping controls how quickly the suspension reacts as it compresses and rebounds, which is what determines whether the car feels plush and floaty or tight and controlled. More clicks toward firm sharpen the response and reduce body movement for track use, while backing off toward soft restores compliance for rough streets. Having 32 steps means you can find a genuine middle ground rather than choosing between two extremes.
Non-True-Type Design
These are non-true-type coilovers and use an OE-style spring and bucket setup. What that means in practice: ride height is set through the spring perch rather than a separate lower mount, so adjusting height also changes spring preload, unlike a true-type coilover that separates the two. This is a common and proven design, and for a street and track car it works well, but it's worth understanding before you buy so you know what you're adjusting. The rear running a separate spring and shock follows the factory E36 layout rather than a combined unit.
Construction and Bearings
The front coilovers use pillowball upper mounts, which replace the rubber factory mounts with a solid spherical bearing for more precise camber and a more direct connection between the suspension and the chassis. ISR Pro coilovers use high-end Japanese bearings, which is the kind of detail that separates a coilover that stays tight and quiet over time from one that develops play and noise. For a suspension component that lives in a harsh environment and cycles constantly, bearing quality matters.
Fitment and Compatibility
These coilovers fit the following:
- BMW E36 (coupe, sedan, and convertible)
These do not fit the E36 Compact. The Compact uses a different rear suspension setup and is not covered by this kit. Confirm your chassis before purchasing.
Who This Is For
These coilovers fit a specific owner. If you've got an E36 that sees both street and track time and you want one setup that handles both rather than a track-only suspension you regret on the commute, this is built for that balance. If you want adjustable ride height and 32-way damping so you can tune the car to your roads and your driving, this gives you that range. If you care about build quality and want pillowball mounts and quality Japanese bearings rather than the cheapest possible coilover, this is the step up.
These are not the right coilovers if you have an E36 Compact, since they will not fit. They're also not the pick if you specifically want a true-type design that separates ride height from spring preload, or if you're building a dedicated race car that needs much stiffer spring rates than the 6k/8k this kit ships with.
What's in the Box
- 2x Front coilover assembly
- 2x Rear springs
- 2x Rear shocks
- 1x Spanner wrench set
Installation Notes
Professional installation is recommended. Coilover installation involves removing the factory struts and shocks and working with the spring assemblies, which requires the right tools and safe support of the vehicle. Set your ride height using the included spanner wrenches, and keep in mind that on this non-true-type design, height changes also affect spring preload. Once everything is installed and set to your target height, get a professional alignment, since ride height and suspension changes always alter the car's alignment and driving on bad alignment will wear your tires and hurt handling.
