The rear springs on the 2001-2006 E46 M3 models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off.

A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time.

The factory BMW springs sell for $140+ each. We sold and replaced enough while working in New England that we were able to get a strong grasp of the issue and come up with our own springs that are an improvement over the factory springs in every way. These springs are made in Germany using high grade spring steel that is then shot-peened for longer life and powder-coated for protection. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

Replaces Coupe models only.

After much anticipation, we are pleased to release our lowering spring kit for the BMW M3 G80 platform! Taking our experience from our highly popular F80 springs, the goal with this offering was to lower the M3 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal. 

Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.

Front Lowering: 1.4"

Rear Lowering: 0.7"

Stock Front Rate: 186 lb./in.

EMD Auto Front Rate: 194 lb./in.

Stock Rear Rate: 608 lb./in.

EMD Auto Rear Rate: 645 lb./in.

Everyone knows the E53 has been notorious for the air ride system to fail. Even BMW technicians will tell you it's not if your air bags will fail, its when. Repairs can become fairly costly as well, with each bag plus labor potential costing you hundreds and hundreds of dollars. Not only that, but the repairs never seem to be permanent, whether its a sensor going off a leaky air bag or the compressor. Get rid of these problems for good, with this Coil Spring conversion kit. Using OEM springs will give you similar ride height as the air ride without compromising handling or comfort.

**Note: Installing this kit will trigger a Self-Leveling Suspension Inactive Light**
