Review on Eibach S90 4 30 043 by Tim Blandin

Just to be clear, these are Eibach Pro spacers that bolt on and are centered on the hub (the two most important things to look for ONLY with high quality spacers). They are built with good quality and material. When installing, be sure to use anti-seize paste on the standard hub and Loctite on the standard studs. Then tighten in a star pattern (torque 85-90 pounds!). Make sure the entire inside of the wheel is in full contact with the spacer surface (back to back). These 30mm spacers ensure that standard studs do not protrude above the spacer surface, which is essential for absolute surface-to-surface wheel anchoring. My only criticism of the product is the packaging. They could have done a lot better and stuffed it a bit more since it was shipped from overseas. In addition, great product and high quality! Well done Eibach!
