Speed Source Polyurethane Engine Mounts, Which are compatible? Options

They don't seem to have an application specific to our generation. Being the kind of bushing it is I'm thinking there should be one compatible, like perhaps the MR2 NA ones. Anybody know?

The kirkosaurus ones work in unison with the stock ones, which means the effective stiffness of the mount in final form is less than the stiffness of the inserts.

A 75A insert along with the rubber mounts could give you a final mount stiffness of, say, 60A.

These inserts are 75A . The way they work is as was mentioned before, these replace the whole mount. So you'd have to press / hammer out the old bushing and press in the new one. The bushing is a complete bushing, so it leaves VERY little room for movement (almost unnoticeable) at the cost of increase NVH over the inserts. The inserts only work best if the mounts are still in good condition.

Getting new mounts + inserts is more expensive than getting these Speed Source poly mounts, so I'm trying to get these instead.

@BonzaiCelica: I was thinking about that, but that doesn't necessarily mean that the bushings on the mounts are the same. That's why I ask. My worry is that they're too small. If the bushings are bigger than the mount, I can just cut them down to size. Guess I'll probably have to bite the bullet and find out if they don't answer my email.
