so, having my car being smacked into by a BMW made me think. The front spindles on the 240z are relatively weak and have a rather weak point that can bend. My car was hit from the side, the other guy's bumper hitting the top of my (well, davyz's actually) rim, and the whole wheel acted a giant lever and bent my spindle. My wheel is now at about neg. 10* camber, with spring partially folder and my illumina likely gone as well.
Anyway, back to the point. I have realized how weak the spindle attachement is to the strut tube, so I was thinking - there's copious amount of space betwee the spindle/brake mount and the strut. Granted, 3200lbs of metal hitting the side of a Z is the most extreme measure... but what if that region was filled? This would prevent eventual wear and possible cave in from hard cornering and maybe that occasional time you catch unwanted air and toast your bearings and possibly bend the spindle. This would also aid those running wider track from wheel spacers. The poorman's way of doing it would be to buy JB weld putty and form a shape to fill that gap. This would prevent the spindle from moving up at all, as there would be a solid piece of steel (or equivalent). JB Weld way would be about $15 worth of jb weld, and an hour work of work including waiting for it to harden. of course, a piece could also be designed to be welded in, which is how it should be done.
I understand that nissan engineers intended for the piece to fold in in case of an impact, which is why the unit is not a solid construction. This would also imply that in case of an accident similar to mine, the brake would also be ruined upon impact, instead of being completely intact as mine was left. Is this a relatively stupid idea, or is it worth putting some thought into? the weld-in spacer would go where the red tint is on the picture.
