Has anyone installed these in their FC Turbo 2? I am in the process of restoring my 10th AE and need replacement covers. Trying to keep it as close to original as possible. When these are installed the old covers are removed?

Not the same brand, but some 16 years ago I picked up a set of replacement leather seat skins from Leatherseats.com that I DIY installed on my S5 T2, which are basically the same seats as your 10thAE, minus any special 10AE logos yours might have. They were doing a discount on the forum at the time, cost me around $500 shipped back then. You do need to remove the OEM seat skins to install them, and obviously remove the seats from the car and fully dissemble/reassemble them to do the job. Wasn't all that difficult, and they still look brand new. Took this picture just now, lighting sucks but it gives you an idea how they look today 16 years later
