Being a New-England based company we see all variations of weather conditions. And we've seen more than a lot of seized coil overs and other metal items that have fallen prey to corrosion and rust. This Winzer Tek Wax is the best defense against corrosion that we have yet to come across. TekWax is a heavy-duty, flexible wax that you spray onto metal surfaces and it forms a durable protective film. It was originally used as a sealant for wheel wells, bodyshells, rocker panels, and chassis panels which makes it ideal for un-coated and exposed metal parts on your car. It has a high-quality matte amber finish that is also slightly tacky to the touch. Another plus is that it can give some components an original OEM appearance. We spray Tech Wax on our coilover threads to keep salt and sand from gumming up the threads and seizing the adjustment collars. We also use it on other exposed metal surfaces that don't have any corrosion protection from their manufacturers (steering hose fittings, even fastners and hardware). The finished surface has an amber (gold-ish) hue that blends in with many other hard parts on the car and it has an overall 'finished' look. TekWax is sold as a 24oz aerosol can. It ships by UPS Ground only. Follow instructions on the can for the best and safest results.

The front springs on the 2004-2010 E83 X3 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. Typically the X3 was popular in markets with heavy salt and moisture anyway and water can pool in the bottom spring pad.

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 $200+ each. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

Sold only as a pair.

This item fits the following BMWs:
