TBH, if it was at a carwash it had probably been used within an inch of its life...
As far as the drilling goes, it's tight but easily done. I got a local metal worker to do it for beer money.
If I'd done it myself, if wouldn't look anything like that...
Just make sure you print the template out at 100%(!), measure thoroughly, and drill 7mm holes for the M6 bolts (as Fanatec suggest).
One last thing... the M6 bolts that come with the Elite are not flat-headed, which stops you being able to have the plate as low and flat as possible, as it forces you to angle one plate up 20 degrees and then the second one down 20 degrees (if you want it level).
This won't be a problem for most, but I like my wheels low and level, so I've used a flatter-headed type of M6 (actually one spare from the Fanatec Rennsport Stand), so that I only have to angle it up/down 5 degrees. The yellow tape that you can see, I just stuck there to protect the mount.
If all this sounds complicated, it really isn't - just have a look at your bracket before installing and it should all make perfect sense...
Oh, one last thing to do is make sure the bolts (after protruding from the 3mm rSeat bracket) are no longer than 12mm, otherwise you'll drill into your lovely new wheel. I just cut mine down with a hacksaw. Again, it tells you all this on the template instructions, but if you're in a rush to race, you might overlook this.
Once done your Elite will look awesome, almost as if it's levitating (especially if the base of the wheel sits a few mm proud of the rSeat mount, as in my template pic).
Sure, you can just use the Fanatec Elite included mount, but if we weren't all perfectionists we'd all still be racing with controllers...
Hope some of this helps,
