I am currently in the process of my D16z6 Swap into my CRX. Before it goes back together, my buddy who is doing it with me talked me into buying the Energy Suspension motor mount polyurethane bushings for the mounts. they just came in today, and i bought them from ptuning.com for $22. I'm just curious if these are a good idea, if they will be too stiff and the car will shake a lot at idle, or if they will be really good and make up for lost horsepower and the shaking won't be that bad. Please give me a little idea of what to expect, or whether or not it was a good idea buying from them. -thanks in advance for any interesting replys.
