Anyone have experience using SPC eccentric/camber bolts?

Seem to be a bit beefier than stock (and hopefully not a consumable like the stock bolts on the front control arms)? Just figured I'd poll the room before buying.

Pretty sure it's not the washers that limit the clamp load, it's the bolt size and the cuts from the threads to make them work. Twist all you like, eventually you just stretch the bolts and make them entirely useless. Once they slip the bolt is yielded and more torque doesn't do anything, they are done and need replaced.

Those appear to have a hell of a lot larger/deeper cut from the diameter, for a lot longer than necessary for no reason. More like the old shitty NA design the better NB replaced. Large single cut and coarse threads, weak as could be made. Do not want.

Washers are certainly not the limiting factor in clamping load (and shorter the length of the fastener the stiffer the bolted joint). Just wasn't sure if they were using a high strength material or not, regardless of any loss of moment of area/diameter from the D cut/coarse threads, but I would imagine that's going to be a solid no given the other design choices.

In any case, definitely not checking any boxes, NB bolts it is.

My washers always fail first. The stupid tiny 2mm tooth gets stripped out then it's a nightmare to align.

I like the idea of these, looks like the S2000 stuff, but the hardware looks cheesy.
