Solid engine mounts ?

Hi folks, is there anyone in Brissie or Gold Coast running those AWR engine mounts, who'd let me peek under the bonnet?
Seriously considering making my own (different) design, and would love to know about plate thickness, etc???ImageImage

I'd also love to know how different they feel. I would assume a bit more vibration? also does it contribute to less driveling loss? If it does I would assume it only translates a small amount?

I guess its for a race car- something rarily used on the road. Why would you substitute a properly engineered engine mount for a plastic bush? It will add a lot of NVH - an engine mount isolates a lot of vibration which really makes motoring hard work. Vibration breaks things as well- including the spirit. The car industry worked hard to actually make cars more amenable to being driven- and a good rubber mount is part of that.

If you install a pair the car will vibrate a lot if you install only one it's pretty livable in a daily Drive but it's nothing like a standard Mercedes people replace them because the factory ones tear very regularly when the car is drĂ­ven hard especially when it makes good power.

I believe the SE mounts are firmer

Mark , who owns The Car Clinic at Southport has a set, or similar, on his Supercharged NA

Whole car has low level vibration at idle. Reduce gearshifter movement by a useful amount, thus improving shifter feel at the expense of having to use Loctite on the shifter bolts because of the vibration.

Mine have the 90 durometer bushings and I did 50,000klms in it on country Vic roads in a year with no complaints.

A quick measurement found plate thickness on the AWR mounts to be 4mm.

Perhaps the hybrid mounts stocked by 949racing would be a good compromise if the car sees the street often?
The hybrid mount package provides one driver's side AWR mount identical to those in OP's pic, the passenger side mount is a Mazdaspeed Motorsport mount with a higher durometer.
Haven't had the chance to evaluate NVH but am expecting a livable compromise between cabin comfort and shifting improvement.

Supermiata. The hybrid kit is made by Supermiata not AWR as stated.

..and 'Mazda Comp' P.S. rubber mount.

Apologies..
