He does not lie. Its real smooth when driving, but at idle its like a huge baby shaker.

Seriously, don't do it. It's not like polyurethane bushings or r-comps on the street, where it's a little noisy. MMRs are full-blown race car shit.

No lie there, the damm keys jingle at idle. Its rough, this is why i choose the mazda comp mounts.

then perhaps the secret to awesome miata mounts is to get some 80 or 90A hard urethane casting compound and re-make your current mounts with it.

yeah a friend of mine was saying something like that using the urethane window sealant to cast my own mounts. But yet he has the billet in his tibby.
