Hello Rudi,This is what I have been owing you guys for some time now. The exact stiffness of the mounts. Here are the specs:
Stock: 50 ShA
Blue / street: 55 ShA (10% stiffer than stock)
Black / sport: 65 ShA (30% stiffer than stock)
Red / race: 75 ShA (50% stiffer than stock)
Maybe some insights from those of you who run these engine mounts?
Tougher idle definitively, but not in a unpleasant way. However I wonder if the TCU should be changed, shifts are not THAT smooth. Opinions?Just took the car for a quick run. Two initial observations... 1) Idle is definitely rougher from a NVH perspective, and notice more vibration in the whole car and steering wheel. Once you push the giggle stick, you really don't notice it 2) The few shifts I did do (local street only), things feel smoother when shifting. Doesn't seem to upset the car balance as much. I definately need more time to truly form an opinion.
@GMS - Stupid question, does that small aluminum spacer go on top of the bushing, or under?
