I am lowered on Eibach pro kit springs .. does anybody know what is the best specs for my setup to prevent any problems ?

 

It might be best to stay within OEM specs. Unless you are running a wheel setup that needs camber to fit, or for track purposes there ins't a need for specific alignment specs.

 

Okay gotcha. Was just curious because, I had a blowout on the back driver side tire about a couple weeks ago and I was told that of course that I would have to buy a new tire to replace it but, it was recommended that I would need to buy a new tire for the back passenger side as well.
