BMW M2 (G87) Coilovers: AST vs Moton vs H&R Compared

The 2023–2025 BMW M2 (G87) is the last rear-wheel-drive M car, and it left the factory heavy — roughly 3,850 lbs riding on adaptive M dampers tuned for showroom comfort. The quickest way to wake up its 453–473 hp S58 chassis is a real suspension upgrade, and picking the right BMW M2 (G87) coilovers is where most builds start. At NLP Performance in Tampa, FL, we help G87 owners weigh full 2-way coilovers against motorsport single-adjustable kits and budget lowering springs — so this comparison puts the AST 5200, Moton 1-Way, and H&R Sport Springs head-to-head with real specs and pricing.

Why the BMW M2 (G87) Needs a Suspension Upgrade

The G87 M2 shares its platform, S58 twin-turbo 3.0L inline-six, and much of its suspension hardware with the G80 M3 and G82 M4, but it carries that mass on a shorter 108.1-inch wheelbase. From the factory it runs adaptive M dampers with fixed spring rates and a ride height set for comfort and clearance. That setup is genuinely good on the street, but it leaves lap time and body control on the table: the nose dives under braking, the tall stance limits camber, and there is no way to corner-balance the car.

A suspension upgrade fixes all three. Lowering the center of gravity roughly half an inch to two inches sharpens turn-in, coilovers let you set ride height and damping for your tires and track, and adjustable links restore the alignment a lowered car needs. In our Tampa shop, the G87 M2 is one of the most common cars on the alignment rack right now, and owners almost always start with one of the five parts below.

BMW M2 (G87) Coilovers & Suspension at a Glance

Here is how the leading G87 M2 suspension options compare. Full coilover kits (AST, Moton) give you height and damping control but replace the adaptive dampers; springs, sway bars, and links each solve one specific problem for less money. Prices reflect current NLP Performance pricing at publish time.

AST 5200 Series Coilovers: The Do-It-All Top Pick

The AST 5200 Series is a 2-way, independently adjustable monotube coilover — the sweet spot for a G87 M2 that sees both the street and the occasional track day. Because compression (bump) and rebound are on separate adjusters, you can run a supple bump setting for broken Tampa pavement while keeping rebound tight enough to control the M2’s mass through a corner. The kit is height-adjustable and fully rebuildable, so it is a buy-once part rather than a throwaway.

Moton 1-Way Coilovers: Motorsport Pedigree for Track Builds

Moton is AST’s pure motorsport sister brand, engineered by the same Dutch group, and the Moton 1-Way Series brings that race hardware to the G87 M2 for about $3,550 — currently a clearance price. The 1-Way name means a single adjuster changes bump and rebound together, which keeps setup fast at the track. These are rebuildable monotube dampers built for lap time first, so the trade-off is a firmer, more purposeful ride than the street-friendly AST 5200.

H&R Sport Springs: The Budget Path to a Better Stance

Not every G87 M2 owner wants to give up the adaptive M dampers, and that is exactly who the H&R Sport Spring set (part hrs28616-7) is for. These progressive-rate lowering springs bolt onto the factory adaptive struts, drop the car a mild, warranty-conscious amount — roughly a third to a half inch front and rear — and tighten body roll without the cost or complexity of coilovers. At $509.15 it is by far the cheapest way to fix the M2’s tall factory stance.

Anti-Roll Bars & Adjustable Links: Dialing In the G87 Chassis

Coilovers and springs set ride height; sway bars and links control how the car uses it. The Eibach Anti-Roll Bar Kit for the G8X M2/M3/M4 pairs a 29mm front and 25mm rear bar — both tubular and multi-position adjustable — to cut body roll and let you tune the balance between understeer and rotation. At $554.00 it is the single best handling upgrade per dollar for a G87 that already has a decent ride height.

Once a G87 is lowered on any of these setups, the rear geometry moves — you gain negative camber and the toe shifts — so an alignment is mandatory. The SPL Parts rear upper camber/lateral and traction links ($809.00) swap the fixed factory arms for motorsport-grade adjustable links with spherical bearings, letting your installer set rear camber and toe back to spec (or to your track alignment) and corner-balance the car. For front camber on a lowered strut, AST’s adjustable top-mount camber plates (around $1,025) do the same job up front.

AST 5200 vs Moton 1-Way: Which Coilover Wins?

For a G87 M2 that lives on the street and visits the track a few times a year, the AST 5200 wins because its independent bump and rebound adjustment lets one car be two cars — comfortable on the highway, planted on track. The Moton 1-Way wins for a dedicated track or time-attack build where a single, fast-adjusting damper and a lower buy-in near $3,550 matter more than daily comfort. Both are rebuildable monotube units from the same engineering house, so neither is a compromise on quality — the decision is purely how you use the car. If you never see a track, skip both and put H&R Sport Springs plus the Eibach bars on the factory adaptive dampers for well under $1,100.

What to Budget for a Full G87 M2 Suspension Install

The parts are only part of the number. Coilovers on the G87 M2 are a job we recommend leaving to a shop: the strut assemblies need a spring compressor, the rear shock access is tight, and the car has to come off the ground evenly to set corner weights. Plan on roughly 3 to 5 hours of labor for a coilover install, or 2 to 3 hours for a spring-only setup. Every install ends the same way — on the alignment rack, where a performance alignment typically runs $150 to $250 and is non-negotiable after any ride-height change.

If you are chasing lap times, budget an extra hour for corner balancing on the AST or Moton kits so the diagonal weights are within a few pounds — that is what makes a lowered M2 turn in evenly left and right. In our Tampa, FL shop we set most street G87s around a 0.75 to 1.25 inch drop to keep the geometry sane, then let the customer decide how aggressive to go from there. Add adjustable links and camber plates only once the ride height is locked in, so you align to a target instead of a moving one.
