    Just installed poly engine trans and dog bone mounts. Have a few questions about them. Firstly how stiff should these bad boys be because I can't even hook up one of the dog bones she doesn't even budge... Trust me I tied off to a truck and backed up didn't budge. Secondly when I drove her home I expected the rattle and such but now she makes some pretty loud engine noises. Just wondering how other peoples cars reacted to the poly mounts and what I should expect from them noise and vibration wise.

    So you ended up getting your dogbones hooked up then..... im guessing you were either on an incline and the engine was shifted back or somethings wrong cus pollys wont keep you from bolting in your dogbones. Can you even run shortened with zzp headers?
