Per request, here’s a list of all the aftermarket kits I know of for the RS5. It should be noted that the RS5 clutch discs and plates may be different in size from the other DL501-equipped cars. I don’t know if the basket size is different however or whether say S6 clutches and discs can fit into an RS5 clutch basket.
Some of the kits are full builds with clutch basket, others are the clutch friction discs and clutch plates. Some of the discs are OEM replacements meaning they have the same or very similar coefficient of friction.
McLeod-This is a full rebuild kit with various gaskets, the friction and clutch plates, etc…cost is $1300 as I reached out to them on it. They mentioned it has 30% more torque capacity than the OEM clutch pack. I also reached out to Raybestos on their discs and they said they are designed as an OEM replacement meaning they’re not more aggressive than the OEM discs. So take the 30% more torque capacity with a grain of salt.
Deka Clutch-This company is out of Russia and they offer three stages for the DL501. I know of at least one individual here in the states running this clutch successfully. Stage 1 seems reasonable and supposedly holds 700Nm (516ft. lbs) as is. I don’t know if that’s with increased valve body pressure but at least one company says the OEM discs are capable of holding 800Nm. The stage 3 apparently holds 1200Nm and uses more friction and metal discs. Looks like they’re using the stock basket but everything is fully rebuilt. I’ll get clarification and add that info here. The stage 2 photos show “Germany” across one of the friction plates but it has more friction and steel plates per clutch pack.
TVS Engineering-This is a company out of the Netherlands who has dipped their toe into all aspects of the DL501 and they have a lot of options available from tunes to clutch packs. I’m still waiting to hear back on what they have to offer for clutch options along with pricing. Had to send them my VIN first. More info to come…Custom Code used to carry TVS stuff but it appears their site is gone (closed their doors?).
SSP Performance-They sell clutch packages, friction and steel discs but not assembled clutches. Says for the S4 but they may fit others. Heard there were daily drivability issues with them but that could have been down to improper clutch slip adaptation.
Exedy-Big time company who has been making clutches for decades. They offer OEM style clutch discs and they separate it into friction and steel kits
Friction Kit part number is EFK415
Steel kit part number is ESK415
Price will vary by vendor.
Borg Warner-Yes, the same company which makes the DL501 is now offering clutch packs. These are OEM replacements so don’t expect them to hold more torque than the original clutch pack. But some interesting info on the page which lends credibility on the S6/S7 having different diameter discs.
