TruHart products are great. I honestly don't know why you would say otherwise.
Hardrace builds all of their control arms, camber arms, toe arms, etc.
They are owned by the same parent company as D2 coilovers.
http://urbanimport.com/I have used a wide variety of their products on a lot of cars with zero issues. I can't testify to the coilovers as I haven't used them but a local shop keeps them in stock and everyone who has purchased them so far has no complaints.
I had all of the arms they make for my EG, I currently have their camber kits front and rear on my TSX. My friends TL on air that I built for him uses everything they offer for a TL (air was from Accuair and Airtekk Truhart didn't make air yet). We have a 350z in my car club that just ordered all the TruHart arms for his Z as well and a 2006 Lexus GS430 on air running Truhart adjustable arms.
