The H&R 29894 is a sport coil spring kit for the Mercedes-Benz E320 Cabriolet (W124 chassis) in its non-self-leveling configuration. The manufacturer's sport springs use a progressive rate, so stiffness increases as the spring compresses, and the manufacturer uses that design wherever the application allows. Compared with a generic budget drop spring, a matched progressive set aims to lower the convertible's stance and firm up body motion in corners while keeping daily-drive comfort reasonable. Searching for W124 E320 Cabriolet sport springs or non-self-leveling lowering coils will bring up this exact part number.
Fitment is the first thing to verify. The part is identified for the 1992 to 1995 W124 E320 Cabriolet without self-leveling, but listings vary on the exact model-year coverage, so confirm your car's year and suspension configuration with the manufacturer before ordering. Because these springs replace factory units, expect a firmer, lower stance than stock. Owners considering a track-day or spirited-street setup should also check the condition of their existing dampers, since new spring rates change how the shocks work.
No. The manufacturer's product designation specifies "w/o Self-Leveling," so this kit is intended only for cars without the self-leveling system. Check your car's configuration before ordering.
Per the manufacturer's technical FAQ, if a spring looks the same on both ends and fits in either direction, install it with the closer coils facing up.
The manufacturer recommends measuring ride height both before and after suspension installation so you can verify the change in height.
This is a coil spring replacement on a strut-and-control-arm suspension, so the car must be supported securely on jack stands and the springs must be compressed with a proper spring compressor before removal. Work one side at a time so you can use the untouched side as a reference for orientation and seat placement. Measure ride height before you start so you have a baseline, then measure again after installation, as the manufacturer recommends. Difficulty rating, tool list, and installation time for this specific kit were not confirmed in the manufacturer's materials, so review the manufacturer's installation instructions before beginning.
