What do you consider a 'modest' poly option?
What stiffness?

I have both upgraded engine and transmission mounts. I think it's worth it.
I don't know if you'll be measurably faster on a track, but the car feels more like one.
With the stock mounts you feel the engine/transmission act like a pendulum, when coming out of say a roundabout where you have that quick balanceshift from left to right.
That feel is completely gone.

But if you go above ~shore 60A, that's considered pretty hard for engine mounts.

I have the vibra technics engine mounts, but if I had to buy enginen mounts now, it would definately be the ones from Powerflex.

As transmission mounts I have generic type A vibration dampners. Cost about $3/piece
