they are cast... light & strong... haven't seen any real bad posts about them except early ones weren't hubcentric (so you would need rings to prevent vibration)... gary sheehan uses them on his racecar and thinks they are pretty good. i have yet to see a post of someone bending one (of course, i haven't been looking for one either)
What are the arguements between forged and cast? I'm assuming that forged is stronger. On the other hand, I hear of people bending their expensive forged wheels and I would rather bend a $125 cast wheel than a $300+ forged wheel.
A forged wheel is often times much stronger than a cast one although you can make a good cast wheel also. The strongest wheel we have ever used is the Volk TE37 which is also one of the lightest wheels you can buy. It is forged though which makes it much more expensive.
I've had the Subzeros on my car for a week now, and have no complaints at all. They roll true, and the price of the package was excellent. $1285 delivered for 17 x 7.5 silver with 225/45ZR17
S-03s. Can't beat that with a stick.
I just got my 17x7.5+48mm Subzeros last week on my wagon. They look good, they feel good, and they rub on my fenders on bumpy roads.
I don't know if I bought the wrong offset, or if my swaybar is interfering, or what. I just had a body shop look at the car and they said they couldn't roll the fenders because the QP is spot-welded to the fender, and they would have to re-weld and repaint. $1000+... no thank you. They suggested I try to get some negative camber into the back that would let the wheel travel more to the inside.
God, I always see you posting that your 17x7.5s don't rub on your wagon... are you sure? Did you do a chalk test? What driving conditions did you try? Are you running with a swaybar, lowering springs, or coilovers?
