It seems that this thread keeps getting linked to as the see all be all, in regards to our clutch kit and our customer service, in which this is only one person's experience.
The break down of this:
Customer lives in Germany, ordered our Stage 3 clutch and had it installed by a third-party. Our Stage 3 disc is made of ceramic. More on that later.
Customer started to have issues after 10k miles of driving and only after long drives.
It is rather hard to diagnose a clutch when you're on a different continent, time zone, and relying on the fact that you're trying to do everything possible to fix it without having to remove the transmission as this will cost the customer money.
After attempts to fix it without removing the transmission became futile, we offered to send another clutch kit to the customer. He choose to go another route and install a Sachs.
We said to ship it back and will warranty it if there was any defect.
We receive the clutch and did an initial review of the clutch and explain our thoughts of what it might be in this thread.
We sent it to Competition Clutch and waited for a response from them. This is what took the longest of the process.
It was deemed install and user error as the clutch didn't have lube on the splines as instructed. The other issue is with a ceramic clutch, material and deposits can become stuck onto the flywheel if the disc is overheated. This happens when you drag the clutch over time, and is the case here.
Even though it was Install and driver error, we refunded the customer.
We have sold near 1000 clutches, and have many satisfied and repeat customers who can get 50k+ miles depending on how they drive.
The problem with clutches, is that they are a wear item, and can last minutes, or years depending on the driver, power, and installation practices.
If you have any further questions about our clutches or customer service, please message me here, or on Facebook as my name on there is Garetto Congello, and I'll be more than happy to talk with you.
