Here’s what you need to know to confirm it’s the right fit for your car.

What’s Included

• Mounts: Four-piece kit—front, rear, passenger, and transmission mounts—plus three mounting brackets.
• Construction Options:
• Steel: Welded solid steel with a black finish (90850 series).
• Billet: CNC-machined 6061 aluminum for a lightweight, premium look (B90850 series).
• Bushings: No-tear polyurethane in 75A (race), 85A (extreme race), or 95A (competition) hardness levels; color-coded inserts (black for 75A billet, grey for 85A, red for 95A).
• Hardware: Includes some mounting hardware; uses some OEM bolts.
• Warranty: Lifetime warranty from Innovative Mounts for manufacturing defects.

Compatibility Details

• Vehicles: Fits 2006-2011 Honda Civic Si (FA5/FD2/FG2/FN2 chassis).
• Engines: Compatible with K-Series engines (e.g., K20Z3 in the Civic Si).
• Transmissions: Works with 5 or 6-speed manual transmissions only.
• Not Compatible: Does not fit K24 Accord/TSX/Euro R transmissions or automatic setups—check your transmission type before buying.

Fitment and Design

• Direct Bolt-On: Installs without hood notching or trimming, using factory mounting points for a hassle-free fit.
• Performance Focus: Replaces fluid-filled OEM mounts with solid steel or billet mounts, reducing wheel hop (wheel bounce during acceleration) and sharpening throttle response.
• Vibration Note: The no-tear bushings minimize vibration, but you might notice slight cabin vibration, especially with higher horsepower or stiffer bushings (85A/95A).

Variant Options

• 75A Steel (90850-75A): Moderate firmness for a balance of performance and comfort; ideal for spirited street driving or light track use.
• 85A Steel (90850-85A): Stiffer for improved dynamics; suits track-focused drivers wanting tighter control.
• 95A Steel (90850-95A): Maximum firmness for high-power builds or competition; prioritizes precision over comfort.
• 75A Billet (B90850-75A): Same firmness as steel 75A, but with billet aluminum and black inserts for durability and style.
• 85A Billet (B90850-85A): Billet upgrade with grey inserts; blends stiffness and aesthetics for performance enthusiasts.
• 95A Billet (B90850-95A): Top-tier billet option with red inserts; built for extreme setups demanding ultimate rigidity.

Installation Considerations

• Skill Level: Professional installation by a mechanic or specialist is strongly recommended due to alignment precision and torque requirements.
• Non-Returnable: Once bolted down, mounts show impressions and cannot be returned—verify fitment first.
• Design Benefits: CAD/CAM-engineered and stress-analyzed for strength and a perfect fit, with no axle bind.

Is This the Right Kit for You?

• Yes, if: You own a 2006-2011 Civic Si with a K-Series engine (like the K20Z3) and a manual transmission, and you want better traction and response for street, track, or racing. Pick 75A for street, 85A for track, or 95A for max performance.
• No, if: Your Si has an automatic transmission, a non-K-Series engine, or a K24 Accord/TSX/Euro R trans, or you prefer a soft, quiet ride over performance gains.
