First off, I really like these seats. I purchased the A4 wide, and had corbeau shave the seats 1" to remove the height problems I had heard about. I am 6'3" 225lb and fit great, the standard A4 would have been fine but my shoulders were too wide for that seat. I can get my helmet on and still have some clearance from the roof, I would say it is very comparable to my stock seats. I did choose the double locking slider bracket so that it locks on both sides, instead of just the one side.

The seats went in pretty well, the rear nuts are tough to get on but can be done. I would definitely recommend a ratcheting wrench for the rear nuts.

Now on to my question, where did people mount the stock seat belt guide? It doesn't seem like there is a spot in the seat for it. I will be running a 5pt or 6pt harness for the track, but don't want to do this on the street. Any help would be appreciated. I also plan on calling Corbeau in the morning to see what they say.
