Your not the only one that has has bad luck with Eibach and thier horrible customer service. I bought a set of sportlines for my camaro years back, the box had all rear springs, I called, they sentfront ones for the 98up camaro, mine is a 96, I put them on so when I let the car down, the front bumper sat a 1" off the ground, was like, sweet, its slammed, then I tried to drive it, the spring rate was so off because of the wieght difference, every bump I hit, the k-member would bounce off the ground, still have the scares to prove it. Lets just say by time I was done beating them up, I had new springs installed and an alignment and paid nothing, they refunded all my money and paid the shop direct. All I said was I was going to put a bad post up on camaroz28.com and LS1tech.com, boy if life were always that easy.
