ECS Tuning Stage 4 Performance Clutch Kit with Lightweight Forged Steel Flywheel (18.85lbs) - ES4620676

All too often most larger turbo upgrades produce power levels that would have required a heavy duty clutch kit that broke the bank (and your left leg). Our ECS Tuning In-House Engineered Stage 4 Clutch Kit bridges the gap in the market between price and torque holding capacity. This clutch kit continues our legacy of designing and creating top quality, affordable clutch and flywheel kits. Now available for your Audi TT or Volkswagen MK4 1.8T platform 6 speed manual transmission vehicles with power levels up to 500 ft/lbs. 

After a lengthy development process of in-house engineering, testing and retesting of multiple prototypes on vehicles with a larger, upgraded turbocharger, we are excited to give you our best clutch kit yet! Our kit is engineered to reliably hold 500 ft/lbs of crank torque and feature specifically selected components for performance and track driving styles. Each kit includes a more reliable, lighter weight flywheel than factory for quicker revs and improved reliability. Lastly, all necessary hardware is included for basic installation, such as flywheel bolts, pressure plate bolts and throwout bearing bolts. We even included a new LUK throwout bearing and a VW-Specific clutch alignment tool for proper crank bore engagement and clutch disc centering. 

PART DESIGN

• CLUTCH DISC

  • 240mm 6-puck ceramic friction disc

PERFORMANCE FEATURES

• With our lighter weight flywheel and performance clutch kit you can expect quicker revs, faster acceleration, improved rev matching, less rev-hang and faster shifts. 

• Lighter weight total assembly over OEM components (8.33lbs savings): 

  • Clutch Disc - OEM 2.45lbs / ECS 4.25lbs

  • Pressure Plate - OEM 10.80lbs / ECS 9.50lbs

  • Flywheel - OEM 28.05lbs / ECS 18.95lbs

  • TOTAL COMBINED WEIGHTS - OEM - 41.03lbs / ECS 32.70lbs

PRODUCT DEVELOPMENT

• From inception to completion, over a lengthy development process and multiple designs tested and re-tested, we are proud to finally offer what we believe is the very best clutch kit in this market, at the very best price! We partnered with a global clutch manufacturer for a performance clutch disc and pressure plate that met our standards and reliably holds 500 ft/lbs of torque. We designed and engineered our single mass lightweight flywheel and sent it out to a third-party balancing company for SFI 1.1 design testing. Although each flywheel is not numerically certified for SFI, the design meets all requirements for SFI 1.1 Certification. 

• Tested on our ECS Tuning MK7 GTI shop car equipped with a CTS BB550 turbocharger that put down an impressive 435 ft/lbs of wheel torque (approximately 500 ft/lbs of crank torque) utilizing our in-house Mustang AWD 500 SE in ground dyno.

• Our Clutch and Flywheel Kits were tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.

INSTALLATION AND SUPPORT

• Looking for installation tips? Look no further, we put together a full installation tutorial from start to finish including how to remove your OEM parts in detail! See our Installation PDF under the INSTALLATION Tab for more information.

• Break-In Recommendations:

  • Recommended break-in: 500-1,000 miles of light throttle city driving staying under 4,500 RPM. Make an effort to shift through the gears as much as possible to evenly break in the clutch and flywheel.

  • Try to avoid over slipping the clutch, such as prolonged bumper-to-bumper traffic, during the 500 mile break-in period.

  • Avoid hard launches or quick shifting until after the 500 mile break-in period has passed.

  • Do not use a clutch pedal stop during break in period 

**PLEASE NOTE:**

• Fitment is for 1.8T engine and 02M transmission combination only 
• Audible chatter from the transmission after installation is considered normal. As with most single mass flywheels there is less dampening in the flywheel to reduce "gear noise." This chatter noise may be more present when the transmission fluid temperatures are hotter and may be intensified by other modifications. Most 1.8T engines with the 02Q gearbox will experience some chatter noise at hotter temperatures. Please be advised that this noise will go away once the clutch pedal is depressed. This symptom may be lessened by adjusting transmission fluid weight, turning off electrical/driveline consumers (A/C, High Beams, ETC.) and by raising the RPM slightly. 
• If your vehicle is still equipped with the OEM Clutch Bleeder Block / Delay Valve we STRONGLY encourage removing the restrictor or purchasing our ECS Tuning Billet Clutch Bleeder Block - ES2586656. If driven aggressively, with the OEM Delay Valve, the clutch disc is highly likely to slip, resulting in permanent wear to the clutch disc, flywheel and/or pressure plate surfaces, resulting in requiring replacement of these components. 
• If used with ECS Clutch Pedal Stop adjustments may need to be made to obtain proper disengagement
