The bilstein shock has a groove milled into the body of the shock which receives a snap-ring type piece of metal. The snap ring seems to be the only thing keeping the threaded sleeve from sliding when pressure (ie; the weight of the car) is applied. To me, it looks like 1/4 the wieght of the enitre vehicle is transferred through that 1/16" snap ring, seems like alot! Is this how all coil over shocks are designed? The spindle has 2 giant "10.9" bolts tying it to the upper control arm, why such huge bolts when all that weight is going through the snap ring?
