Mugen 4-Piece Engine Mount Sets — BACK IN STOCK!

S2000 owners, it is time to tighten up your drivetrain response and put your power directly to the pavement. We have officially restocked the highly sought-after Mugen 4-Piece Engine Mount Set at King Motorsports, available right now with FREE SHIPPING within the continental US!

Priced at $539, this complete 4-piece replacement set is engineered from a significantly stiffer hardened rubber compound than your soft, worn-out factory OEM mounts. By drastically reducing engine twist and drivetrain deflection under hard acceleration and high-RPM shifts, these mounts deliver dramatically improved throttle response, crisper gear engagement, and enhanced stability through the corners—all without the harsh, excessive vibrations of solid polyurethane bushings.

Product Highlights:

Hardened Rubber Compound: Specially formulated by Mugen to stiffen the drivetrain while maintaining streetable cabin comfort.

Enhanced Dynamics: Eliminates slop in the engine bay to provide sharper throttle inputs and more predictable weight transfer.

Complete Overhaul: Includes all four matching mounts required to refresh your chassis setup.

Price: $539 with FREE SHIPPING straight to your door!

Confirmed Heritage Fitment:
• 2000–2003 Honda S2000 AP1
• 2004–2009 Honda S2000 AP2

If your F20C or F22C is still sitting on original, cracked factory rubber, you are losing valuable feedback and power transmission. Upgrade to authentic Mugen track-tested engineering today.

Mugen MDCF Forged Wheel Sets — ALMOST SOLD OUT!

We have only a few sets remaining of the Mugen MDCF Forged Wheel Sets, and they are ready to ship with FREE SHIPPING within the continental US!

Mugen engineered the cutting-forged MDCF specifically to complement the aggressive lines of the modern FK8 Type R chassis. We have not seen a set of these on a new FL5 but think it would make the right build look incredible. Moving away from standard cast layouts, these massive 20 x 8.5 +45 5x120mm wheels weigh in at a nimble 23.5 lbs. each. By utilizing a high-intensity cutting-forged manufacturing process, Mugen achieved superior structural strength while dropping unsprung weight—giving you sharper steering response and better track handling.

Finished in an eye-catching two-tone black mirror face, these wheels combine a polished machined surface with premium glossy black paint to deliver an unforgettable premium presence.

True Forged Strength: Lightweight construction that reduces unsprung weight to 23.5 lbs. per wheel while maintaining maximum rigidity.

Premium Two-Tone Styling: High-end black mirror face finish that creates a sharp, head-turning look.

Optimized Offset: Precision spec measuring 20 x 8.5 with a +45mm inset and a direct 5x120mm bolt pattern.

Mugen FL5 Group A Sports Exhaust Systems — ONLY 2 LEFT!

FL5 owners, looking for the ultimate combination of factory-engineered exhaust efficiency, weight reduction, and aggressive sound? We have a massive update: the highly anticipated Mugen FL5 Civic Type R Group A Sports Exhaust System is in stock and ready to ship, but our supply is critical—we only have 2 units left available!

Crafted entirely from premium, high-grade stainless steel, this system was developed under Mugen’s strict design philosophy to extract maximum power from the K20C1 engine while shedding unnecessary weight. It trades the factory triple-tip setup for a commanding, ultra-smooth 94φ center-exit finisher. While the profile remains clean and purposeful, the tip features a laser-engraved “Infinite MUGEN” logo to create a powerful, unapologetic motorsport presence on the rear of your CTR.

Engineered to maximize exhaust flow volume and throttle response while significantly cutting down structural weight.

Features a prominent 94φ center-exit tip adorned with laser-etched “Infinite MUGEN” branding.

Comes complete with a genuine active exhaust valve canceler (to prevent dashboard error lights) and the specialized Mugen rear muffler garnish for a seamless, factory-level bumper fitment.

Fully certified replacement muffler system that complies strictly with safety and pre-certification standards.

With only 2 systems sitting on our warehouse floor right now, this batch will be gone in a flash. Don’t wait on a months-long overseas container cycle to wake up your FL5’s true sound.

Thank you to our very own for the great photo!
