I had them in my sig for a while. I ran them on my crappy (hard to balance) steel wheels.
They did OK. I must say that a mix of them + static balancing is awesome though!!!
I wouldn't run them again, if you were to ask me that. I like conventional balancing better, seems to be more consistent. It's the same price, but I like when the machine reads 0 and I get a smooth ride.
I may try them again, just for craps and giggles, but I am undecided at this point.
I want to eliminate all variables and try them again though. I'll probalby run them when I put on boggers...
