The Ultimate Guide to Honda S2000 Suspension Parts: Upgrades, Replacements, and Buying Tips

Whether you're restoring a Honda S2000 to its former glory or chasing lap times, the right suspension parts can transform how your car feels. With decades of aftermarket support, choosing components requires understanding what each part does and how it fits your goals. This guide covers the essential Honda S2000 suspension parts, from coilovers to bushings, with practical advice for street and track use.

Understanding S2000 Suspension Geometry

The S2000 uses a double-wishbone front and rear suspension, a setup prized for its camber control and responsiveness. While stock parts are reliable, they have limitations. Many owners find the factory damping too soft for aggressive driving or the rubber bushings too vague. Upgrading suspension parts can sharpen turn-in, reduce body roll, and improve feedback—but balance is key. Too stiff, and the car becomes skittish on bumpy roads.

Coilovers vs. Shock and Spring Combos

Coilovers

Coilovers are the most popular upgrade for the S2000. They replace the entire strut assembly with a threaded body that allows adjustable ride height and, often, damping. For street use, look for a dual-purpose set that maintains compliance. Top brands like KW, Ohlins, and Bilstein offer models tuned specifically for the S2000. Expect to spend $1,500–$3,500 for quality coilovers.

Shock and Spring Kits

If you prefer a simpler setup, pairing aftermarket shocks with lowering springs can improve handling without the complexity of height adjustment. Brands like Eibach and H&R make progressive-rate springs that lower the car about 1–1.5 inches. Pair them with Koni Yellow or Bilstein shocks for a cost-effective upgrade—around $800–$1,200 for the set.

Sway Bars: Reducing Body Roll

Sway bars (anti-roll bars) are a cost-effective handling upgrade. Stock S2000 bars are thin, leading to noticeable body roll. A thicker front bar reduces understeer, while a rear bar can dial in oversteer. Adjustable bars let you fine-tune balance. Popular choices include Karcepts, Cusco, and Eibach. For a street car, a 22–25mm front bar and slightly smaller rear bar work well. Installation is straightforward, but note that stiffer bars can increase bump sensitivity.

Control Arms and Camber Adjustment

When you lower the S2000, rear camber becomes excessively negative, causing tire wear. Adjustable upper control arms allow you to realign the rear suspension. For the front, offset ball joints or adjustable lower arms can correct camber. Brands like SPC, Hardrace, and Buddy Club offer strong, reliable arms. Expect to spend $200–$500 per pair.

Bushings: Tightening the Chassis

Rubber bushings soften the ride but introduce slop. Replacing them with polyurethane or spherical bearings sharpens steering response. Common wear points are the front lower control arm bushings and rear knuckle bushings. Polyurethane is a good compromise for street use—stiffer than rubber but not harsh. For dedicated track cars, spherical bearings offer maximum precision but transmit more noise and vibration. Energy Suspension and Whiteline make full bushing kits.

Springs: Lower and Stiffer

If you keep your stock shocks, upgrading springs can reduce body roll and improve stance. Progressive springs offer comfort while lowering. Linear springs give consistent rates but can be harsh on rough roads. Swift, Spoon, and Eibach are respected makers. Drop amounts range from 0.5 to 1.5 inches. Remember that lowering too much can bottom out and cause bump steer.

End Links and Tie Rods

Upgrading end links (especially for sway bars) reduces slop. Adjustable end links allow preload adjustment and prevent binding. Moog and SuperPro make durable replacements. For steering, aftermarket inner and outer tie rods eliminate play. The S2000 is sensitive to tie rod condition—worn ones cause vague on-center feel. Look for OEM-quality or upgraded spherical joints.

Subframe Reinforcement

High-mileage S2000s often develop cracks around the rear subframe mounting points. Reinforcement plates welded into the chassis prevent this. While not a visible suspension part, they are essential if you track the car or use very stiff springs. Beatrush and Cusco offer bolt-in braces that also stiffen the rear.

Brake and Suspension Integration

Suspension upgrades affect braking. To take full advantage, consider upgrading brake pads and lines. Stainless steel brake lines reduce pedal mush and pair well with stiffer suspension.

Final Recommendation

For a street-driven S2000 that sees occasional autocross or canyon runs, start with adjustable sway bars and high-quality shocks with lowering springs. This combination reduces body roll and sharpens response without breaking the bank (around $1,200–$1,800). If you want more capability, invest in a dual-purpose coilover set from KW or Ohlins ($2,000–$3,000) and add adjustable control arms for proper alignment. Avoid track-only parts if you daily your car—they compromise ride comfort and can be harsh. Always prioritize a good alignment after any suspension change. With careful selection, your S2000 will handle better and remain enjoyable for years.
