Its always a hard one, if you get it wrong it gets expensive.. And there are not as many S5's around running 1740 sort of power which require a specific clutch to hold the power.
I was on JHM's case for months and then gave up, personally if they are going to release soon, I would wait for it. I asked EVERYONE, sure they make a clutch but the ones that did said they were heavy on the foot and not OEM like as I wanted, I understand there is going to be a compromise but I didn't want something to be a pig on the street.
If you have any other questions please ask, the Eurocode stage 3 is still in there but is no good, I actually just sold the car (still talk to the new owner) and that was one of my breaking points, I was just over it! They were happy to take my money but blame the install on why the their clutches are rubbish, it's also not just me, others have experienced the exact same characteristics as I did.
JHM are also a pleasure to deal with, wish I could say the same as Eurocode.
I as nearly going to buy the Stage 4 JHM but they wouldn't sell it to me knowing I would be back, which I appreciate.
I have driven a Sachs equipped RS4 1740, and it was fine, last time I asked they didn't make anything suitable, maybe ask them again?
