Performance: I 100% noticed a difference, Id say a lot more then a strut tower bar but not as much as a better sway bar. You can def feel the car has more stability in the corners (and boy did I test this out properly). You can also feel the chassis a bit more stable as well again you can definitely feel the difference.

Cost vs Performance: $75 dollars isn't much in terms of car mods you can barely get a crappy strut tower bar for that much so yes its 100% worth the cost.
