Message I just got my Tomei exhaust cam gears in the mail (staying with modified adjustable VTC cam gears for the intake though) today and it got me wondering. Do people have problems with the cam gears slipping at all and getting off of where you set them at? Just looking at it to me, it seems like they would with all of the power that goes though those 5 bolts holding the adjuster part on. i would imagine they would slip often to be honest...but then again, I have no experience with them. They are only held in place by the torque you tighten the bolts to and no other lock washer or anything. Do you think that adding a lock washer to the mix would add extra security, or is this something that, while seeming like a possible problem, never is? just wondering, and I'd love to hear other opinions from people who have messed with these before. If you all suggest lock washers, I'll pick some up tonight.

Oh and also, since I am majorly majorly majorly anal about looks along with performance, I went ahead and changed the adjusting bolts and washers on them from gold colored 10.9 bolts to black 12.9 bolts. I know this is something super minor, but to me nothing on my car can get missed, and little things like color themes not matching drive me nuts. Also, while doing so, I upgraded the strength of the bolt a little, which obviously can not hurt at all since it takes so much abuse.

New bolts and washers on right, and old on left.

Thanks,
Mike
