I am sure that Vuong install them correctly. He would never make mistakes on installing a common part that he's done plenty of times. I even came by to help and I know they were installed correctly. I hope that you are aware of that after market springs and stock shocks on most cars cause shocks to blow a lot faster and easier. I remember you had springs that dropped your car pretty aggressively, that puts the shocks more vulnerable to blow. Did you drive aggressively around any rough roads? Hit a big pot hole or hit one at high speeds? Vuong has never had one complaint on the cars that he has worked on, you seem to be the first one.
