They fit perfectly. Im about 1.5" lower with the rail setup we did, and with the flatter head rests im much more comfortable in a helmet. I also only track 4-6 times per year but wanted better seats regardless. Im tall (6'2") so i really needed them.
After a VERY long wait I finally got my AMX Performance Recaro CS. Absoutly insane how good they look and how well they fit. Need to find someone who can code out some errors for me otherwise theyre perfect.
YES.
I just went to install mine and they have the same terrible fitment youre seeing.
Did APR ever reply to you? I hit them up via email and IG and am interested to see if theyll do anything about it.
This times 1000. Go because its free then go with one of the better groups (Chin or PDG)
You'll quickly feel like theres a club you aren't a part of, and you're causing everyone greif just by being there.
As for the track, the Supra does great on it. But you'll be lucky to get one good lap in...
