The last time I checked, Eibach did not make any springs for my '79 107, and I don't want to lower the car. That's why I checked out other sources. I would love to find cheaper springs but so far I've only found the one's from John Olsen. And I do agree $795.00 for 4 springs aint cheap, but like I said that's all I've found. Correct me if I'm wrong. sbr, '79 450SL, 74,000mi
