Updating just for posterity. Installed both cp-e engine mounts on my 2015 R.
I had the also buy the Racing Line coolant relocation kit. since the cp-e had no mounting location for it
Other issues I ran into with the CP-E mounts. You need to have crows foot wrenches to properly get at a few of the bolts.
The screws they supplied to attach the battery tray to the mount do not fit. I don't know if the GTI battery trays are different or if the 2015 model is different but I had to use my own bolts to attach to the mount.
Otherwise, the mounts feel good. I have about 150 miles on them. NVH is probably 5% harsher. Its about 20% harsher on cold start but when you put it into D, its fine. Shifts feel good. I used to think I had a basketball rolling around under the hood but my old mounts had 105k miles on them. And I can't confirm it but I feel like it changed my engine note just slightly. I also gained 5hp from the coolant relocation kit.
