PRODUCT DETAILS
Hasport rear differential mount kit for the 2000–2009 Honda S2000 (AP1 and AP2) running the stock F-series engine. This Honda S2000 Hasport kit replaces the factory rear diff mounts with much stronger 00–09 S2000 Hasport mounts that actually hold up to hard launches, sticky tires, clutch kicks, and real power gains.
The factory S2000 diff bushings are a known weak link. After 15–25+ years, the OEM rubber usually cracks, collapses, or rips completely. When that happens, the differential walks around under load. That slop is where the sketchy wheel hop comes from. That’s why you hear the rear end clunk on and off throttle. And that’s why shifts start to feel vague once you add power or bolt on real tire. If your S2000 feels loose out back, the S2000 differential bushing kit is usually where you start.
These Hasport rear diff mounts use 6061‑T6 billet aluminum brackets with high-grade urethane inserts to lock the rear diff into position. Once you bolt in this S2000 Hasport mount kit, the diff stays put, so the driveshaft and axles stay aligned and loaded the same way every time. In the car, that means cleaner launches, more precise shifts, and way less wheel hop when you really lean on it. If you’re tightening up a tired rear end or building a serious track-focused S2000, this Hasport S2000 bushing kit fixes a real mechanical weak point instead of band-aiding it.
Bushing Stiffness Options
Hasport S2000 mounts come in four urethane hardness levels plus a solid option:
- 62A (Street) – SKU: HAS-APDIFF-62A
Best pick for a street-driven S2000 that still sees spirited driving. Ride quality stays close to stock, and you won’t hate your life on long freeway runs. You’ll feel a little more drivetrain feedback through the chassis, but it won’t rattle the dash apart. Ideal if you daily the car and just want your S2000 rear diff mounts to stop squirming. - 70A (Race) – SKU: HAS-APDIFF-70A
Good fit for a dual-purpose S2000 that hits occasional track days or autocross. You’ll notice more vibration at idle and low RPM, but the diff stays planted when you mat it or clutch-kick. This is “serious enthusiast street car” territory—firmer than 62A without going full race car. - 88A (Extreme Race) – SKU: HAS-APDIFF-88A
Now you’re into dedicated track-car behavior. These Hasport S2000 replacement mounts hold the diff almost like a solid mount, which sharpens response and keeps things consistent when you’re on R-comps or slicks and making real power. In exchange, you get a clear bump in NVH—expect more gear noise and vibration inside the cabin. - 94A (Most Extreme Race) – SKU: HAS-APDIFF-94A
For cars that basically live at the track or drag strip. These are the stiffest polyurethane Hasport rear differential mounts in the lineup. They work well with high-grip setups, aggressive clutch dumps, and S2000s making big horsepower. Streetable? Technically. Comfortable? Not really. - 6061 Solid Aluminum – SKU: HAS-APDIFF-6061
No urethane at all—just solid 6061. This turns your S2000 differential mount replacement into a fully solid-mounted rear. Maximum stiffness, maximum feedback, maximum noise and vibration. Great for serious race builds and big-power cars launching on slicks. For most street S2000s, it’s overkill and will get annoying fast.
Whether you’re freshening up a worn rear end, finally dealing with the wheel hop that’s been bugging you for years, or building a full track-spec S2000 around a stronger Honda S2000 mount set, this S2000 Hasport mount kit turns the back of the car into something tighter, more predictable, and way more confidence-inspiring—exactly how an S2000 should feel when you drive it hard.
