Finally on the market, DiFtech's articulating rear spring perch for E46 M3 and 3-series! This kit is the absolute best way to convert your stock rear spring setup into an adjustable performance setup. The ride height adjuster is moved to the under side of the rear control arm for easy adjustment without removing the wheels. The adjuster is made with spring detents to give adjustment reference points and to hold the adjustment in place while the spring is unloaded. Most importantly, the spherical mounted articulating spring perches eliminate the angular influence that the rear control arm has on the spring as the arm swings, allowing your linear race springs to stay linear. These DiFtech units are completely free to articulate all the way down to the minimum ride height setting, where you're likely to run most race cars. Similar products on the market use a cone-in-cone design which locks down at lower ride heights and doesn't swing at all.

 The spring-on-arm location on the E46 chassis is great for minimizing shock bind and freeing up room in the rear wheel wells, but it comes with its own problems. As the suspension is compressed and the arm swings upward, the locating angles of the upper and lower spring faces change. This results in the spring loading unevenly and, therefore in a non-linear fashion; meaning that your carefully chosen spring rates aren't doing what they're calculated to do. This articulating perch system eliminates that problem and allows linear race springs to work in their free state, resulting in a more planted and predictable back-end of your competition M3. Under-body adjustment is a breeze with a simple 14mm hex and detents every 1/4 turn. If you are looking for quality rear ride height adjusters for your track E46 build, look no further.Â

Note:Â Check your rulebook for your specific racing class compliance.Â

DIFtech only recommends using this kit with 5" or 127mm long springs for proper ride height range. This kit includes 65mm spring retainers. Custom diameter sizing available upon request.Â
