upr control arms

I have not used QA1 or UPR at all but im giving my experience from the way they look, and the structural integrity and welds seems like they would be dangerous for street use, drag use, im sure they are great, they are super light, strong enough for what they need to do, but street use or handeling use they just seem well, cheap
 
i got a upr k member control arms and coilovers im puttin on my car...i got all upr rear tubular control arms i installed last year and loved them so the BS rumors of UPR is not true...and if u got defective parts send it back anf they give u a new one..is keeps your wheels in the stock location also....Get the UPR K member u will be satisfied
