Just got off the phone with SPEC tech and sales, I thought everybody might like to know:
SPEC makes a full range of kits for 05 LGT 5mt ---with the stock flywheel---.
stage II is rated at 400ft lbs at the clutch. ($539 with shipping)
Now the other half of the information: I called SPEC first because they provided excellent service, advice, and the perfect product for my last big budget project (2003 A4 V6 + Supercharger).
Today I was asking about longevity: Our clutches may last 5k miles or 400k miles depending on use of vehicle. I pointed out that a previous rep (a few years ago) pointed me at a specific clutch because of high life expectency as it would be compared to a stock clutch. Also that I was very happy with that product. His response was that clutch life will rely entirely on how I drive my car. I asked if he could compare the expected life of their clutch not in miles but in general relation to factory clutch lifespan. Some of our customers replace it for wear at 5k miles and are happy that it holds the power.
I think for a clutch that costs over $500 and has a life expectency of: "5,000 to 400,000 miles" I'm going to spend half that on another OEM clutch and take a chance on replacing it again next year.
