Hardrace makes a street and racing version. If my research is correct:
- OEM durometer 55 (Source = Spoon)
- Hardrace Street version 55-60
- Hardrace racing version 65-70
- Megan Racing 70
- Spoon mounts 70
- J's racing 66
- Mugen might be 65

Hardrace:
Street version: http://www.hardrace.com/Product_detail.asp?id=1074&Car_Make=7&Car_Model=23 &Car_Type=43
Racing version: http://www.hardrace.com/Product_detail.asp?id=1073&Car_Make=7&Car_Model=23 &Car_Type=43

I went with Spoon, since they are cheaper than Mugen and also come with a reinforced transmission brace.

PS. don't forget about the option to install the Spoon engine mount rings. They fit any OEM style engine mount and turn them into solid mounts, not for street use!

 

^^Good info. Thank you.

 

Had hardrace. Yanked them out and returned to stock.

with a supercharger OEM is the way to go

 

Which hardrace set did you have? I would think a stiffer set of engine mounts would be better for a supercharger set up, because of the added weight that makes the engine top heavy. I have a vortech supercharger on my car and will be installing the spoon motor mounts. I also have a NRG engine torque damper with a puddymod bracket set to street mode.

Also, Megan Racing mounts are 70 Durometer.

 

Is the Spoon transmission brace any better than OEM? The Spoon looks slightly beefier but that's only based on one photo some side by side photo I've seen on some sites.

 

I just put on the Hasport 62A street mounts in. The original OEM mounts were completely broken in two. I can't believe that the motor don't just walk off. They are much stiffer than stock. The car feels very solid and shifting is great. Hopefully they will loosen up after they are broken in.

 

Yes, and it's a nice bonus when you buy the spoon mount set. It has a welded on gusset plate on the inside(top) of the OEM brace. A better option is the ASM Transmission Stay GT ASM Transmission Stay GT « Autobacs ASM Yokohama. I sold the spoon brace and went with the ASM one, because it had a thicker gusset plate, the plate covered the whole part and it had much better welds. You could pay a fabrication shop to do the same thing for less though.

That ASM is nice but way too expensive. I am leaning toward either Spoon or (edit) Vibratechnics for engine plus the OEM or Hardrace for transmission.

 

I have the Vibratechnics. Vibrations and engine drone is increased about ... 25%? over OEM. Just enough to be irritating at times, I'd say.

 

i had the street ones. Other than making the car vibrate more, fresh OEM mounts are better
