Understanding the S2000 CR Suspension
The S2000 CR suspension differs from the standard S2000 in several ways: firmer springs, retuned dampers, and a larger front anti-roll bar. These changes were designed to improve cornering grip and reduce body roll. The CR also came with Bridgestone RE070 tires and a unique wheel offset, but the suspension itself is the main focus for parts lookup. Understanding the differences is crucial because using standard S2000 parts on a CR can alter the ride and handling characteristics.
Key OEM Suspension Components
When searching for S2000 CR suspension parts, focus on the following components:
- Front dampers (shock absorbers)
- Front springs
- Rear dampers
- Rear springs
- Front anti-roll bar
- Rear anti-roll bar (if different from standard)
Honda uses specific part numbers for the CR variant, which are often different from the regular S2000. Below are the part numbers for the 2008 S2000 CR (the only model year). These numbers are based on official Honda parts catalogs and verified by enthusiasts.
Front Suspension Part Numbers
Front Damper (Shock Absorber)
- Left: 51605-S2A-015
- Right: 51606-S2A-015
These dampers are specific to the CR and feature different valving than the standard S2000. They are sometimes listed as "CR" in the description. Note: The part numbers may have been superseded by newer revisions, so check with a Honda dealer for the latest number.
Front Spring
- Part number: 51401-S2A-951
This spring is identified by a blue paint mark (or other color code) to distinguish it from standard springs. The CR front spring is about 10% stiffer than the standard.
Front Anti-Roll Bar
- Part number: 51300-S2A-305
The CR anti-roll bar is 22.2 mm in diameter, compared to the standard 21 mm. This part is shared with some other Honda models but is confirmed for the CR.
Rear Suspension Part Numbers
Rear Damper (Shock Absorber)
- Left: 52605-S2A-015
- Right: 52606-S2A-015
These are also CR-specific. They are inverted monotube dampers, identical to the front but with different mounting.
Rear Spring
- Part number: 52401-S2A-951
The rear springs are stiffer than the standard S2000, with a green paint mark.
Rear Anti-Roll Bar
- Part number: 52300-S2A-305
This is the same as the standard S2000 rear bar (16 mm) because the CR did not change the rear bar size. However, verify for your specific vehicle.
Aftermarket Considerations
While OEM parts are ideal for restoration, many owners opt for aftermarket suspension upgrades. Brands like Öhlins, Bilstein, and KW offer coilover kits that improve performance. If you are replacing a worn OEM part, consider whether you want to stay original or upgrade. Keep in mind that switching to aftermarket may require other adjustments (e.g., alignment, corner balancing). Always use a reputable brand and follow installation instructions.
If you need to order OEM parts, your best bet is a Honda dealership or an online Honda parts retailer. When ordering, provide your VIN to ensure compatibility. Part numbers listed here are for the 2008 model; if your CR is a different year, double-check because the CR was only produced for 2008 in the US.
How to Verify Your Part Numbers
To confirm you have the correct parts, look for these identifiers:
- Paint marks on springs (blue for front, green for rear)
- Stickers or stamps on dampers
- Measure spring wire diameter and free length
- Compare part numbers with the ones listed above
If you are buying used parts, ask for photos of the part numbers or markings. Counterfeit or mislabeled parts exist, so be cautious.
Final Recommendation
For owners of the S2000 CR, using the correct OEM suspension components preserves the car's intended handling and value. If you are replacing worn dampers or springs, order the part numbers listed above from a trusted source. For those seeking better performance, consider aftermarket coilovers specifically designed for the CR or standard S2000, but be aware that they will alter the ride. Always verify part numbers with a Honda dealer using your VIN before purchasing. Maintaining the CR's unique suspension is key to enjoying one of the best-handling production cars ever made.
