Coil-overs and mechanical stress?

Jhill

So I went oem style as this was part of my concern as well and also the coil overs I went with don’t have a true type option so that made that easy. That said one thing MCA pointing out when I was considering going that route is that the cars bottom out bumper are on the shocks in oem setup so when the car bottoms out (which is more frequent with oem softer suspension) all the vehicle weight is sent to the strut towers which is a lot more force then hitting regular bumps at speed. So this does make sense to me especially if the z uses longer mcu bump stops on the shock in oem form as many manufacturers do which makes the bumper act as part of the suspension by adding progression and not just a limiter (I forget if they did or didn’t when I removed stock suspension). For me I only change ride height when going to a track day and in those situations I’m already swapping brake pads so I’m kind of in for a project anyway so the added time of being oem type isn’t too big a deal but I am kind of jealous of the ease of adjustment on true type. I do wish there was more clear answer on if you should preload the oem type or not, some manufacturers say to preload the springs and others say not to. In oem suspension the springs are not preloaded but then the shock have more stroke to play with too.
