You may have been going faster than you thought.
If this page is correct use .71 for 5th

I don't know the height of your tires, but here's a calculator. Your rearend ratio should be 4.10.

I'm not sure what tires you have on the rear, but you could look up your tire on line or just measure. I'm not sure if the tire grows in height around 200 mph, but I'd imagine you could add a fraction of an inch.
24.7 inches tall 202 mph
25 inches tall 204 mph
26 inches tall 213 mph
Careful you're just about at the blow off the road speed. Though the FD has incredible coefficient of drag and minimal frontal surface area it's down force may be a bit challenged..
Sorry to be like a dad, but we care.

Nice!!!!
how much of a difference is there once you go over 170???? I'm gonna guess its pretty much the same...things just go by a bit quicker - lol
congrats on the huge set of cojones!!!!!

Im not trying to act like a parent towards you cause you're an adult and you make your own decisions but its not only so much about your car "feeling" stable, you can have a tire blowout, lose control due a small imperfection in the road, or other things that can lead to a fatal crash.
I remember one time my friend was driving his 01 chevy extreme and those things are slow, he was trying to top it and it would only go 95mph. I guess that was the factory limit and he just tried to hit 100 and the truck shut off completely.
And you know when a car is off and you turn the wheel a bit, the steering wheel locks? Well that happened to him at freaking 95mph. The damn steering wheel locked on him and i dont know how he stopped safely. I guess it was an empty highway cause if there were some cars around, he would def crash into them.
Just be careful man.

lost traction was due to too much downforce on the nose...if it was from poor surface, then what about all the other cars that run on the flats? if you watch the vid in slow mo, you can see the nose dig.

i drove my fd to 160 and the car felt very stable. im sure some R compound tires, a rear diffuser, a wing, and some front canards and you should be ok. i'm not saying do it but it would decrease the risk. i'm assumeing he had the GTC front when he did this which should by mazda design added down force to the front.

I didn't realize how much more gear the FD has. We had my buddy's CYM TII to a calculated 173. 9000rpm in 5th gear, speedo already wrapped around....lots o fun!
He had a ported motor, 3"dp and exhaust, hks bov, stock tmic, fpr, external wastegate, and a full suspension
