You get what you pay for, The JHM clutch is OEM it will last a very long time and while giving you all the holding capacity you need. Also If your doing the work yourself 1000$ for a clutch job for is a steal of a deal especially considering the quality of kit your getting. What your paying for from JHM is the aluminum flywheel. It is bad ass and will significantly help your acceleration. The clutch is factory and pretty inexpensive but its made by Audi for the Rs4 so will handle anything the 3.0 will ever have. Also not trying to be rude or anything but if your that concerned over a couple hundred price difference you bought the wrong car. Its really important to use the right part because it will cost you far more having to replace the part again in the near future, (ask me how I know). The RS4 clutch kit and flywheel will be good for the life of the car, the flywheel can be resurfaced and the RS4 disc is cheap to replace and should last the life of the car if you use it properly, Its a prefect street clutch and is more comfortable than any other clutch I’ve driven.
The clutch from the factory is a Luk, so using a valeo is pretty much downgrading from what the car came with. The place I bought a new clutch kit with new dual mass that I ended up selling on here to another user before I installed my CM kit, from it was like low 700 something shipped from a place called Carolina clutch but I dont see it on there site anymore. Might want to try give them a call. You should at least be using a factory replacement.
