The best Honda S2000 aftermarket parts start with the chassis’ biggest weaknesses: coilovers (the Tein Flex Z is the go-to street setup for AP1/AP2), a cat-back exhaust like the HKS Hi-Power for the F20C/F22C’s signature top-end scream, and brake upgrades to match the grip. Whether your S2000 is a weekend canyon car or a daily driver, these three categories transform the car without hurting its reliability.
The 2000–2009 Honda S2000 (AP1 and AP2) remains one of the most rewarding driver’s cars ever built, and the aftermarket has had two decades to perfect it. This collection covers the full platform: suspension (coilovers, alignment parts), exhaust systems tuned for the high-revving F-series engines, brakes (rotors, pads, lines), drivetrain upgrades, interior pieces like steering wheels, and aero.
What to look for: suspension geometry matters on the S2000 — pair coilovers with a proper alignment from a shop that knows the platform. Exhausts are a taste call, but titanium-tipped systems save weight and suit the car’s character. And because many S2000s are now 15+ years old, refreshing worn bushings and brake hardware often improves the car more than any single “upgrade.”
Popular brands: Tein (suspension), HKS (exhaust), BLOX (drivetrain), StopTech (brakes), and JDMuscle (interior and aero).

Honda S2000 Parts FAQ
Do AP1 and AP2 parts interchange?
Many do, but not all — suspension, some drivetrain parts, and exhaust fitment can differ between AP1 (2000–2003) and AP2 (2004–2009). Check your year and model before ordering.
Do I need a tune for an S2000 exhaust or intake?
Bolt-ons like cat-backs and intakes generally don’t require a tune on the S2000, though a tune unlocks more from combined modifications.
Are coilovers hard to install on an S2000?
Moderate difficulty — a competent DIYer with jack stands can do it in a day, but a professional alignment afterward is essential on this chassis.
What’s the first upgrade for a stock S2000?
Most owners start with tires and suspension, then brakes. The stock F20C/F22C engine is already excellent — chassis upgrades pay off first.
