    yeah that's what I've done for now.

    Yeah I will get a quote, but would wait till fall to ship them off. And yeah, part of the "fun" for me is DIY-ing and saving some $$$. I assume shipping alone would be $25-$50 bucks for the struts, plus a few hundred for shortening not to mention being unable to hear VTEC kick in for some time . Maybe I should buy some 8611 race inserts instead at that point... Well, if I start tinkering with some top mounted plates, I'll be sure to update the thread with progress.

    John you make a good point about being limited in adjustment by the clearance hole and spring seat interfering.
    Harold, I am thinking for the plate underneath, I might just cut the center out of some stock top mounts that I have laying around since they are OEM fitment.
    In the end, is that easier, more cost-efficient, and roughly as effective as getting the Konis shortened?

    I don't know the cost or time involved but another member here was offered free shock shortening. Granted, IIRC, that was a result of a one-to-one conversation at PRI with MCS but, I believe, the rationale for free service was that motorsports-focused shocks should accommodate a lowered car.

    This style camber plates were available for Subaru's as well. I also made a set for a local STF Mini a few years back.

    If you go this route: 1) make sure you have as much coverage as possible on the under side (ie spread the load). 2) Try to get the top to fit flush with the tower sheet metal (not on stand offs like in your pic). This will help support the tower to minimise distortion.

    You will need to come up with a top "spring seat" that will reach the camber plate, the THAT running through the hole in the tower is what will limit your adjustment range. So work out THAT detail first to make sure you have the adjustment range you need before doing all the other work.

    Top mount plates are for sure available for the 944. Those pictures look like how I'd do it with the plate on the bottom of the tower. I wouldn't want to just use nuts and washers down there, but I think with a plate the same footprint as the original mount, you'd be fine.

    Edit: This is how Ground Control does it for the 944.

    Increasing suspension travel on a Mac-strut

    So, my RSX is pretty stroke-deficient, especially the front end when lowered. I'm thinking about ways to increase my strut travel without sending in my Koni's to get them shortened. Beyond adding caster (which barely adds any travel), one idea I came across was modifying or making custom camber plates that mount on top of the strut tower, instead of underneath like stock/standard.

    I am a bit worried about increased/focused load on the strut tower, and potentially damaging it, so I think some reinforcement would be necessary.

    Has anyone done this? Am I making sense? Pics of someone else doing this back when RSX was in STF.
Working...
