LuXun,
You must be one hell of a Dynasty Warrior Fan ! hhaahah..
Anyway, I tried doing the total package from Trial on my ex-car. And its real sweet after that. I for one cannot tahan the tatatatatatatata.... hahahah but after reshim.. cars felt smooth... after pulley.. HAH ! Vroom... you won't lose your top end. but low end is nice. You won't regret it.
But you can rest your worries with Trials, they DO know what their doing.. just that, maybe their staff are not competent enough.. hahahaah just kidding.. don't kick me William !
