You sir, are officially fucking stupid. Just because he has isis equipment doesn't make them shit. I personally know the guy who tests isis products. I'll pm you his name and his shops phone number so he can actually educate you. I personally have no first hand experience with isis products, but i do know 10 cars of the top of my head who run a wide variety of their products without fail and see them on an almost daily basis. People like you are the reason why new companies can't make a name for themselves. I'm going to pretend i'm you for a second, and say that just because the only place you can get Kei Office coilovers is Japan or eBay, they're fucking trash, i'm gunna get name brand megan shit bro. I've witnessed and driven cars with isis BOV's at 1.5 bar. Notice how i said carS.
