I believe YaYa's stuff is lifetime warrantied too.

I'm a bit suspicious, I'd ask your mechanic how he knows they are blown. If he does not show them to you and point something out (it would be obvious if they were), he's probably saying so because of the extra shaking in the car now.

 

but you cant "blow" a motor mount, and any mech with some sense wouldn't say that a motor mount blew.

 

I'm on my 3rd year with my yaya mounts, aside from a little dust, they look at good as day 1.

 

i did come across a set of 4 months old front and rear mounts that were ripped appart on a supercharged v6 tib...
the 4 "legs" inside the bushings were ripped out
and yes, the mounts were properly installed

 

Did Kspec ever reply to you?
