Description:
A long sought-after solution to the most common issue that comes with lowering your Z-Car using lowering springs is now available! This kit includes components to cover one pair of struts: two pillow ball strut mounts; two upper spring seats; and all the required installation hardware. Read on below for more details!

If you have lowered your car with lowering springs (like our Eibach Performance Springs), and are using an aftermarket bump stop (such as our urethane bump stops, 23-4196), you may have noticed that your car bottoms out easier while driving aggressively under some road conditions. The normal way to solve this issue would be to trim the bump stops, which allows for more suspension travel, but also puts your struts at risk of damage (not a good situation, especially if you just purchased a set of our new Koni Struts!). This kit properly solves the problem of the lost suspension travel without sacrificing the lowered ride height by raising the bump stop position inside the spring seat. By doing this, the struts will be able to utilize most of their intended travel, which can prolong the life of the cartridges.

Not only does the kit replace the stock spring seats; it also changes to a pillow ball type strut mount. This type of upper strut mount has been used for years to eliminate deflection inherent to standard rubber insulators. The benefits of this design range from improved tire grip and general handling to more accurate wheel alignment, which further improves handling and prolongs the life of your tires as well! The pillow ball also functions as the strut bearing for the front suspension, which removes both the stock front strut bearings and the rear strut spacers (which is what allows the increased suspension travel).

Note:
This kit will increase feedback felt through the suspension, and may increase road noise and vibration a bit (almost all suspension upgrades do to a degree). Based on overall design and quality of the pieces, we do not think it will be all that significant for most Z-Car owners.
