Where are you getting your solid Engine Mounts from?

I wish I was driving!
I turn them myself (or I did until my lathe got stolen). They are god-awful simple to make.
I wouldn't use them in a street car, for those considering it. The gain is ridiculously minute over poly mounts, and the vibration is far greater.

oh yea, how bad is it? worth it at all?
i have been in 87GTRs and i believe he has Scalli's solid mounts. i'll have to ask BDC. i didnt notice it so much as the big half bridge port.
i have grown to accept scath's word and will do so now. thanks man.

I just don't see the point for it. The difference over poly is so tiny as it just doesn't make sense, where as the gains in vibration are significant.

i asked scalli about making rubber end caps for the mounts and he started to explain why it was a bad idea. i wish there was a good way to do this. he said the reasons for not doing it are somewhat technical and that my pea-sized brain would shut down about 3 seconds into the explanation, so just left it at "its not a good idea." at this time i smiled and nodded.

Unbreakable (important in racing).
Zero percent deflection for instant throttle response. (important in racing).
I would estimate poly bushings do 99% of the latter task without the associated NVH. No one would ever be able to tell the difference by driving, so why bother with solid mounts for the street?
Casio... the rubber is not such a hot idea since the stud itself would transfer the vibrations anyway (easiest explanation without going ahead and describing the detrimental axial loading on the rubber sheets).

Did you change your MSM name or something? Cause I never see you on anymore..

Uh, immovable implies the twisting torque force ends up going to somewhere else. There's a chance you end up stressing and breaking something else.

I saw 23racer and 84 Racing's car last night. I just realized that I should have asked where they got/made It from. I'll enquire on these next time I find myself there passing wrenches and what not.

So, you are not keen on having these on a non-daily driven FC than Ted?

The solid mounts also mean more shock and torque will be transmitted through the drivetrain, and I think the weak point in the system now is the rear diff "ears". These have been known to crack and fail pretty regularly - mostly from drag racing.
I do run the competition mounts on my car now, and they do an admiral job of keeping the noise & vibration down but allowing a little play for engine shifting.

Given that, what are your (Ted) comments about the 13B engine brace? (forgot who sells it... )
