    Strut mounts and super stiff (relatively) springs

    so i'm running Progress sport springs and i'm moving to H&R race springs to help me in autocross. I also am using koni insert struts. Now, i had to hog out the sleeves in the oem mounts, along with cut the bushings in half to allow the nut to thread on with the cone washers in place.

    Is there anyone out there that has used these struts? it seems there were possibly multiple iterations of Koni inserts through the many years of Saturn.

    Will the stock mounts survive OK with the H&R race springs? i understand there is a limit before they just get pounded to death. The stock mounts now i am pretty sure i have sheared the rubber, but i know the fronts were OEM rubber (17 years of use...)

    The downside of using the stock mounts is that the spring is supported by a relatively nonrotating platform (the upper spring isolator, which is rubber/steel) versus having a spherical bearing ANd the thrust bearing that has a hat which lets the strut AND spring move freely, versus just the OEM thrust bearing).

    I imagine if i was to make a strut mount that fit the Koni's i would have to machine a bushing AND a upper spring perch so that the strut would pass through the bearing and allow the nut to thread, and allow the spring to not sit on the mount itself.

    the alternative is using a generic poly bushing to have a slightly compliant bearing that won't wear out in a year... yet allows the strut shaft and spring to pivot from the mount with relative freedom..

    thoughts? really exciting about these spring,s looking forward to higher ride height (better LCA angle ), better ground clearance and more grip from available camber

    While a fun thought process, in my opinion I would just adapt the Raceland coilovers or whatever and just set your ride height up where you want it.

    I think the easy button is definitely to adapt coilovers.

    I don't know how the upper side of the front strut bearing attaches to the plate, but the best solution I can think of is to make a custom top plate (add more caster/camber while you are at it) with a top mount bearing/ball joint in the center and put the bearing/rubber part back in place below that.

    The rubber part is hard as a rock. I'm not sure if its overmolded aluminum or what, but I would have little concerns about fatigue on that part.

    Pretty sure it's overmolded. Over time they turn into domes. But hey free lows!

    The part that domes is the steel plate, not the spring seat.
