hi i was wondering the kspec bushing says recommended for front and back not sides but there pics are of sides and if you do all for you will feel vibration so i was wondering for 300 or more hp are the front and back bushing ok if i dont get the sides or should i get all of them

 

I have the front and back bushings, David cant get ahold of the sides right now so I have been told . On an Inline engine you get very little side to side motion and more front to back. The ones he has listed on the site even though the pics are wrong are the front and back ones.

 

If you want a easy fix, grap a few tubes of urathane at a windshield shop. Then, remove your engine mounts and fill them with the urethane. Allow a good 30h to set and bingo. The results will give you about 80% of what a real urethane bushing would give you...for under 20$.
