wont work.. they tested it on a prius there for all testing is invalid to real world results.

Iirc garagestar was supposed to come out with a kit of a sort but i don't think it ever materialized. Maybe Ken can chime in on his results if they ever got into the prototype stages

Yeah, I'm still very much in the skeptical tent. While the premise may be sound, I just cant see how these would do anything in the real world. With proper torque on all the subframe bolts, it should be rigid and not shift around. The subframe may 'settle' a fractional amount after installation, but it shouldnt move around unless you have a massive impact (that would likely throw off other geometries.

On our LeMons car, we notch the front knuckle to gain more camber in the struts and torque down as usual. Even after 8/16/24 hours of endurance racing, hitting curbs and such, there is no appreciable movement. So on a subframe with 4 points (or more) of contact, well like I said, call me skeptical.

i will say the one nice thing about these is your subframe will settle into the exact same place if you are removing it often. first comes to mind are bmw subframes and they have a fat guide to ensure the sub frame goes back to where it was and doesnt mess with alignment. iirc the miata tub is pretty damn flat where the subframe touches.

I think it's a little more applicable when you have bushings in your subframe.

that seems even more worthless. real results would be removing the stock bushings for solid aluminum bushings.

I'm probably wrong somewhere a long this train of thought, but both the washer and the solid bushing will inhibit the same directions of movement right? Isn't there some worth to just loosening sub frame bolts, taking one bolt out at a time, dropping a washer in each one and re-tightening?

If you go the solid bushing route I imagine you have to detach all the suspension parts, drop the subframe, push everything out with a press, hone the holes to fit whatever fancy custom spherical bearings, push those in with the press, reattach everything, and bolt it back up into the car?

I've seen 240sx people use this type of collar. However these are designed to take up slack within the OE bushings if they are worn out and have slop. Yes, a lot easier than a full bushing swap, but if your car doesnt have subframe bushings, I believe there is little point to those.

I would go polyurethane bushings first.
