Well i just installed the engine mount in my 2006 mazda 6s and i can definately feel a big difference. I knew there was suppsed to be some vibration in the pedals and all from reading up on the mount but when i get up to about 2800 rpm's and higher i have a huge vibration in the gas pedal. Is this the vibration they are refering to or did i fuck something up. I didnt use the spacer they provided because it wouldnt fit. the mount fit perfectly with no space between the mount and bracket. Also i reused the black triangle bracket from my stock motor mount.
