Just thought I'd throw my 2c in.
I bought these a while ago, .5s for the front and side and 1.0 for the trans.
It made everything feel nice and solid. There's a TINY bit of vibration (probably coming from the trans mount), but it's only at idle. All in all, I love em, great purchase.
The only thing is that I did NOT use the bolt they gave you for the side motor mount. If I did, I had no place to put the wires that were bolted onto the top of the original bolt, so I just used the original bolt again (after I had cleaned it up).
