Who have these here and what's your experiences with them. How much vibration do you have at idle or when the a/c is on compared to filling them in with epoxy. I did the epoxy mod and it was like a earthquake in the car. When i got off the clutch it was like the interor was about to fall apart. My dash was literally shaking, but dam the shifts were ****ing excellent (excuse my fench) and there was like double the torque lol it was nice. I chirped only at 4500rpm i never chirped that low before and the car was just excellent i loved how it felt once you were going. I want to get that feeling back or close to it but have no vibration of less noticable vibration. Sorry for the long *** paragraph ^
