I'll answer for him.
Vibrations through the car.
Lots of soft arses on here already moaning about them.
they're crap, ALL you ever need is stock mounts with a powerflex dogbone - OPINION
"The term is widely used informally, with people being described as 'experts' in order to bolster the relative value of their opinion"
Yea vibrations fact that my suspension top mounts sound like there getting ripped apart and knocking like mad from where engine is so stiff and every time I let of the throttle the whole car inside vibrates like mad. If it was used for track would be fine but I Neva do track days and is my daily driver.
Is 75quid really the cheapest ul get a standard upper Engine mount from??
