INTRODUCING THE JHM B8-S5 4.2L V8 FSI PERFORMANCE CLUTCH!!!

After two years of research, development, prototyping, and testing we are finally ready to release our long awaited Performance Clutch Kit for the B8-S5 with the 4.2L FSI V8! We began developing this kit in 2011 and have already installed it on several cars. We like to test all of our products for an extended period of time to verify the durability and longevity of the part before selling it publicly.

WHY THE JHM CLUTCH KIT?

Our Lightweight Flywheel and Clutch Combo comes with our JHM B8-S5 Performance Clutch. This clutch kit features an upgraded, OEM Luk pressure plate with an increased clamp load of over 150 pounds more than the OEM pressure plate while still retaining the self adjusting clutch mechanism (SAC). Increased clamp load leads to greater torque holding capacity without the use of overly aggressive clutch disc friction materials.

CLUTCH DISC OPTIONS: For the clutch disc, we have 3 different options to run with our lightweight flywheel and clutch combo:
STAGE 1: Our Stage 1 Disc is the OEM B8-S5 organic disc. This disc - paired with the increased clamp load of our upgraded pressure plate - gives the best compromise between increased holding power and maintaining the OEM feel of clutch engagement. This is recommend for stock or near stock vehicles with basic bolt-on upgrades that aren't driven aggressively.
STAGE 3: Our Stage 3 disc is a Ceramic and Metal Backed Organic disc meaning that the material that contacts the pressure plate is an organic material with metal integrated into the material. The side that contacts the flywheel is ceramic. This combination of materials will give you a much more direct engagement as compared to the stock disc, while still remaining very easy to daily drive. This clutch disc is recommended for FULL BOLT-ON cars that are driven aggressively and/or light duty track use.
STAGE 4: Finally, our Stage 4 disc is a Ceramic and Kevlar disc. Kevlar is the material facing the pressure plate and the ceramic material is facing the flywheel. This disc will engage slightly more aggressively than our Stage 3 disc and is still very streetable. The Stage 4 Disc will give you the most torque holding capacity over all three setups. The only downside to this disc is the extended break-in period. See below for more information on the break-in procedure.

INSTALLATION INSTRUCTIONS AND TORQUE NOTES: These are NOTES ONLY are not a substitute for factory installation manuals or technical expertise. They are to be used a supplemental guideline only. We always recommend that an experienced technician perform ALL clutch and flywheel installations. For shops or individuals who have access to factory manuals but not factory tools, here are some tips and guidelines we have used to complete this job without the factory tools:
- The JHM Lightweight Flywheel installs in the same manner as the OEM Flywheel. Follow the OEM installation and torque procedures.
- Aligning the clutch disc, pressure plate, flywheel assembly: Install the throwout bearing/sleeve onto the transmission. For alignment of the clutch disc it is easiest to put the flywheel face-up, place and align the disc splines on center with the center bearing in the flywheel, put the pressure plate on top, visually check that the disc is still on center, and begin to tighten and torque the pressure plate. The pressure plate bolts need to be secured with red, high-strength Loctite. Make sure the pressure plate bolts are tightened in a star pattern at multiple torque intervals. This is to make sure that the pressure plate diaphragm or fingers are not distorted upon installation. Once the pressure plate is fully torqued to the flywheel with red Loctite to factory specifications (18 ft-lbs, in intervals), the clutch, pressure plate, and flywheel combination can now be slid onto the transmission as you would a torque converter on an Automatic Transmission. If the assembly will not slip on the transmission, this is most likely due to the fact that the disc is not on center. Remove the pressure plate and attempt to re-align the disc. **NOTE: We've successfully aligned the assembly by following the above procedure. It is not that difficult to "eyeball" the alignment.
- Once the clutch and flywheel combo are installed in the transmission, the half-shaft can be re-installed (this prevents the clutch and flywheel from falling out of the transmission while attempting re-installation). Install and bolt the transmission to the engine. Install the JHM supplied bolts for attaching the flywheel to the flexplate. Torque the flyweel to flexplate bolts to factory specifications. This is done in a similar fashion to torquing down a torque converter to a flexplate on an Automatic Transmission.

BREAK IN PROCEDURE: Clutch break-in is important and must be done properly.

During the break-in period ALL racing activities, launching, or aggressive driving that get the clutch hot MUST be avoided!!! For the Stage 3 clutch clutch disc you need to drive about 500 miles of city type driving. Each time the clutch disc is disengaged and reengaged slowly - basically, whenever you start from a stop or shift it aids in break-in. Because of this, highway mileage does not count. For Stage 4 clutch discs you need to drive about 750 miles of city type driving. Due to Kevlar's resistance to wear, it takes longer to break in.

OPTIONS: There was a VIN split for the throwout bearing and guide sleeve on the B8-S5 4.2L V8 FSI. Early cars up to VIN 8T-8-032000 had one style while Late cars from VIN 8T-8-032001 and up had another style. NOTE: When looking at a VIN, the 10th digit (or the 8th digit from the right) indicates the model year. The VINs listed show a split in the 2008 model year. So if you have '9' in your 10th digit, your car is a late car for the purposes of this split. If you have an 'A' in your 10th digit, you also have a late car. 'A' in the 10th digit designates a 2010 model year ('B' would designate 2011, 'C' = 2012, and so on). Be sure to select the correct split for your car's VIN from the dropdown below.

NOTE: For those that are looking for a more robust, race oriented clutch setup we highly recommend looking into our R-Series line-up that does not have an SAC. The SAC in OEM and other aftermarket pressure plates work great for comfort and OEM-like drive-ability, however it is not designed to take excessive abuse of track days or aggressive street driving. We have done rigorous testing since 2012 to develop the ultimate clutch solution for both street and track and the R-Series is what is needed to take these cars to the next level.
