Anybody know what ET/mph a single layer firejacket is good down to?

I'd rather buy the 75 dollar single one than the 150 dollar multiple. basically the multiple might be overkill since i think my car is only good for a 10.00 pass anyway with the 8 point bar and 5 point harness in it.

sooooooo, anybody know??

 

10.00.

Dont need the $$$ stuff until 9.99

 

sweet, just ordered the RCI single in black from thunder, 60 bucks can't beat that to quit getting hassled at the track
