Dang dude, you dropped the F-bomb 9 times in that video. I hope the Recaro replicas are decently made. Honestly, I wouldn't waste the money on a GT Spec rear trunk cage. Maybe just put in an MX6 rear strut tower bar but the way the GT Spec rear cage is built is pretty flimsy unless you drill out the mounting locations by the trunk and upgrade the hardware. But I kinda laughed when you said you were pissed you had to drill holes into the chassis for the roll bar. Did you expect double sided tape? lulz
However I noticed a significant increase in chassis stiffness after I pull my bar in. It really tightened up the car. And they do look cool.
