The biggest issue is shipping it overnight each way like I did. I spent $120 per direction to get it to the guys that do my diesel sled pulling clutches, and get it back overnight. The cost to actually do the job is small...
Assuming you could stand the ground shipping (2-4 days each way) and have your car down, or assuming you order a new clutch (About $150 for a brand new core) you would not care about the week lost...you can do it for about $300 like I did. Now with more time, and if I get a flywheel to send them also, we can get rid of the POS self addusting LUK pressure plate and make an entire new plate with a diaphram style that can also add plate load. We would be able to support 475-500 EASILY. The current design and plate load with our friction materials will support upto 380-400 with the combo I am running (More street friendly) or 425-450 with a hard core....who cares about grabby clutches....all out assult on friction material.
If I feel spendy this spring or summer, I may send the parts to them and look at doing a double disc slipper clutch that can take crazy amounts of "feathering" the clutch...this would be great for 6000 RPM drag racing launches where the driver could apply power as he saw fit for 5-7 seconds with no fear of overheating the flywheel, disc, or Pressure plate at all. THis technology is what allows a 4x4 truck to chain to a 28,000 lb competition pulling sled and bring the turbo upto 70-80 lbs of boost and use the clutch to get things going without putting the fire out in a big nasty diesel cummins or duramax. Same thought process would allow us to launch an AWD car that wont spin 4 tires while holding max boost and max TQ by letting the clutch do all of the hard work.
If anyone becomes interested in a clutch, feel free to give me a call, PM, or email. And if you want to do it fast and dont care the cost....with overnight shipping it can potentailly leave you Monday, at the shop Tuesday with AM delivery and be back out overnight that same day to you on Wednesday!
Also, this is NOT voiding my warranty. My dealer removed the old one, and is installing this re-lined OEM clutch and they are fine with it. SOme dealerships may throw a fit over it, I make no claim for or against that fact....but my experiance is that a clutch disk.... similar to a set of brake pads is a NON WARANTED, NORMAL WEAR ITEM. As such you can replace a non warranted, normal wear item with any brand you choose unless the manufacturer supplies this normal wear item to you for life of the car/truck for free. My dealer agrees. He is not handing out free brake pads, oil filters, or clutch discs!!!!
